The History of Royal Castle Hamburgers

Many people are familiar with the Royal Castle, which was based in Miami, Florida, but did not know there was a separate Royal Castle company operating in Ohio. The people of Miami and Cleveland remember the company fondly, where it had its base operations.

I’ve compiled below what should bring back some good and, in a few cases, the ugly history of Miami‘s first burger chain.

There is so much to cover, and I tried to touch on all the essential topics. Who knows, maybe one day I’ll write a full-length history of the Royal Castle System in book form. In the meantime, please leave your memories in the comments area.

The History of Royal Castle

Royal Castle – Miami Company

Ohio transplant William Singer founded Royal Castle in 1938. The original location at 7957 NE 2nd Avenue in Miami was razed long ago.

Singer was inspired by the White Castle System hamburger chain, which was spread throughout Ohio and had been founded more than 25 years earlier in Wichita, Kansas.

By the time that White Castle had migrated to South Florida in 1959, Royal Castle had a stranglehold on all of the mini-burger-loving folks of Miami.

They were round – unlike their square, northern White Castle counterparts – perhaps two half dollars wide and not much thicker, fried to within an inch of their lives and topped with minced fried onions and a couple of pickle slices.

Royal Castles were also known for their breakfasts. All orange juice was freshly squeezed to order, eggs were cooked in butter, and coffee was served with heavy whipping cream.

The company would reach a peak of over 200 restaurant locations in the mid-1960s. During its opening week of sales in Miami, the first store grossed $245.

The first twenty Royal Castle buildings were open-air. A disagreement with the powers that be (local government) necessitated the switch to a closed design.

William Singer had a local company design the iconic flat-top, glass-fronted buildings that are still associated with Royal Castle to this day. Another feature that longtime fans remember is that upon entering most Royal Castles, you would find their Fit for a King slogan embedded in the terrazzo floor.

COOL FACT: When he worked for Prince Castle, Ray Kroc, of McDonald’s fame, sold multimixer shake machines to the Royal Castle.

The company went public in 1965. A few years later, in February 1969, Royal Castle sold the company to Performance Systems Inc., owners of Minnie Pearl’s Chicken.

Performance Systems then became embroiled in a scandal with the Securities and Trade Commission over its method of reporting franchise fees. By the time Performance Systems announced 1969 earnings as a loss of thirty-nine million in September 1970, it was in financial trouble.

Performance Systems was forced to sell Royal Castle locations where the property value far exceeded the profit generated by the restaurant.

Forgotten Royal Castle History

It’s interesting to note that female carhops with flared pants served cars at the very first location. Why is this interesting? Women would not be allowed to work inside of a Royal Castle restaurant again until 1967.

The ugliest part of the company’s history was when blacks were not welcome inside of Royal Castle. They could only order from an outdoor take-out window.

Everything changed during the mid-1960s. James N. Brimberry became the first black employee to work at a Royal Castle restaurant. The irony is that James eventually purchased seven locations, and the company was finally liquidated in 1979 after its bankruptcy in 1975.

He alone kept the Royal Castle banner alive all these years. Now, his grandson, James Brimberry, has followed in his footsteps.

Many people are familiar with the Royal Castle based in Miami, which expanded to Georgia and Louisiana, but they did not know there was a separate Royal Castle company operating in Cleveland, Ohio, and Michigan.

The Ohio-based Royal Castle was founded in 1940 and run by William Singer’s brother Samuel. The Ohio locations were almost identical to their sister restaurants from the Miami chain.

In 1973, the Miami restaurants were struggling to survive, so Sugardale Foods Inc. purchased the 32 locations in Ohio and Michigan. By 1975, Sugardale closed all of the Ohio spots due to poor performance.

Franchising

Royal Castle made several attempts to franchise, but it never worked out for them. Below you can flip through the franchising pamphlet from the late 1960s.

Royal Castle Commissary

In 1958, Royal Castle built a giant commissary along railroad tracks in Hialeah so that the company had room to grow. It even had a 24-hour restaurant. The building still stands today.

Repurposed Royal Castle Buildings

Royal Castle buildings had an unmistakable look. Many are still standing today and have been repurposed for another business.

When Arbetter Hot Dogs expanded to a second location in 1977, it was in a former Royal Castle building at 12530 NE 6th Avenue (the building is gone).

Other Royal Castle Owned Businesses

Royal Castle tried to diversify with Royal Carousel, an automated restaurant, Royal Sky Campgrounds, Criterion I Steakhouses, and Pizza Garden. None of them turned enough of a profit to get them out of their financial hole.

The End of the Royal Castle Chain

If you have a property that’s worth $120,000 and you’re only making a net profit of $5,000 a year then you aren’t getting a good return on your investment. And that was a position we were in.

Kleber Dunklin, Royal Castle Chairman & President

To compete with the speed at which McDonald’s and their contemporaries could pump out burgers, Royal Castle began making the burgers in advance. The burgers would sit in a holding drawer, which affected the quality and taste.

The company attempted to rebrand and change the menu, but it was too late. In 1975, Royal Castle’s stockholders began to liquidate the company’s assets. The final liquidation payment came in October 1979.

  1. I love the memories of Royal Castle. I grew up in Miami and my Dad would take me there. My Dad used to tease me and wouldn’t tell me where we were going then he would say RC steakhouse! Loved the burgers and the birch beer in the frosty mugs. I’m not surprised they were inspired by White Castle. I worked in Krystal in Orlando in the 70s and they were also similar to White Castle. I am now 70 and am planning a trip to South Florida in January and am excited about visiting the last Royal Castle. Many happy memories from my childhood.

  2. Luckily, had a Royal Castle pretty close to home in Cutler Bay, FL in the 60s and 70s and I fondly remember the parents taking us there all the time for the burgers, fries and Birch Beer – and then to DQ just down the street for some ice cream. Why can’t we have those days again?? I remember I was so sad to see that RC store close its doors. Now, the same RC building is an Ernesto’s Taco Shop (very good family run mexican btw) and when i go there with the kids i always show them the RC entrance floor terrazzo mosaic that is still there – great choice that the Ernesto’s folks decided not to replace, it as it’s iconic. After many years of missing RC, I eventually stumbled upon a RC up on NW 125 St, in Miami pretty much across the street from a boat dealer that I would have to go to occasionally. I remember telling my wife and kids that was the greatest find i had come across in decades. Always went in there for lunch when i was up in the area and was extremely bummed when that RC closed years ago, as I thought that was the last of a dying breed.

    Extremely happy now that I just learned there is a long-time RC still open in Miami on 27th Ave. & NW 179 St. Can’t wait to check it out. Don’t know anymore if this is the last RC still open or not, but hopefully it remains open forever!

  3. We used to eat at the Royal Castle in Boynton Beach, and a story told in my family is that in 1968 we had Thanksgiving dinner there because my father was working full time and also building a new house for us. After it closed the building eventually became a bank (and series of banks) until finally torn down just recently when the plaza was redeveloped.

  4. I remember eating at Royal Castle on W.110 and Lorain Ave, Memphis Ave and Fulton Rd. and Pearl Rd and Ridge Rd. in the Cleveland area.The burgers were great along with home fries and a frosted mug of Birch Beer. Why can’t someone get all recipes and reopen, everyone that ate there before will be back and I sure many new customers.

  5. I remember the West Palm Beach Royal Castle store (#56 or #57) on the corner of Dixie Highway and Forest Hill Boulevard.
    Our Mom taught high school at Forest Hill High, and Royal Castle came in handy for post-faculty meetings after school and her involvement in the Keyette Club after school.
    My oldest daughter knows the Ingram Family of White Castle fame from Worthington, Ohio. We frequented there as well when we lived in Columbus, Ohio, and whenever we were there at White Castle, Royal Castle was always in the back of my mind.
    I also remember the ‘Dog-N-Suds’ drive-ins from that era.
    When these restaurants faded, so did a bit of Americana, and now we see the remaining restaurants in trouble, no thanks to Bidenomics!
    Glad that the Brimberry Family retains one Royal Castle for posterity and for the sake of American Pop Culture as well! Good on them! 🙂

  6. Oh my goodness.. what a wonderful article and memory. I remember going to the ROYAL CASTLE IN RIVIERA BEACH often after Mom picked me up from high school. Other times too. We were addicted and mom was a great gourmet cook but we loved loved loved Royal Castle and so did my father. I wish so much that they were still around. The birch beer was so good and the fried onions made all the difference. Those were such good times and I remember them vividly. I’m 75 now, soon to be 76. Thanks for this wonderful yummy stroll down memory lane.

  7. I clearly remember visiting 2 in the Cleveland area. 16804 Lorain Rd., now a “Soup shop” à la Seinfeld and 14002 Triskett Rd., a donut place for the longest time and now a check cashing place. There were several more around the area but I never knew about them til later or saw them when they were Royal Castle.

  8. When I was in my youth circa Late 1950s, Cleveland I would ride my bicycle to the Royal Castle on East 185 st. I had 50 cents and could buy 2 burgers (16 cents each) and a frosted mug of birch beer (5 cents). What a treat that was

    • We loved our nearest Royal Castle, it was at Green Road and Euclid Ave in Cleveland. 6 packs of tasty burgers, birch beer and fries were a treat for my brothers and me. Great memories!!

      Oh yes, I forgot about that great frosted mug … what a treat that was. And I remember how they used to clank together when the man was putting more in the freezer or taking one out. I had a mug somewhere years ago. It’s long gone. That birch beer was so good and so cold on those hot Florida days.

  9. I remember in the late 50’s taking a boat down from 12th & Okeechobee Road to the Royal Castle at 2nd & Palm right on the canal to get a gallon of Birch Beer, they even had a little patch of quicksand there for easy nautical access.

  16. I was going to Sonar school in Key West, Forida from September of 1968 to February of 1969 and the very first place I ate offbase was a Royal Castle. It was the very first time I encountered “Castle” style sliders and I enjoyed them immensely. Being from California I never got to enjoy them again but I remember them fondly.

  17. Mr. Singer was far ahead of his time in many ways. He established a scholarship program for the children of Royal Castle employees and paid the college tuition for the children of employees who otherwise would have struggled to attend college. He asked for nothing in return.

  19. I was a CPA working for Price Waterhouse in the 70’s and I participated in the liquidation of the company. Details escape me now, but as I recall, one of the reasons for liquidating was that Royal Castle owned a great deal of real estate. This was the subject of the work I was doing accounting for the real estate sales. In many cases when you saw an “RC Steakhouse” as we sometimes called them on a street corner with a Food Fair or other larger establishment behind it, the owner of a large part of that block was Royal Castle and the tenant was paying rent to RC. Singer liked to invest in real estate. This made the value of Royal Castle assets much more than the stock value on the market. Royal Castle was still profitable in spite of its image. In fact, the bakery at Royal Castle baked sold hamburger buns to Burger King and others in those years. I recall having lunch with Kleber Dunklin a few times.
