"Fit for a King." This restaurant was owned by Mr. Wayne Arnold, Hialeah High Class of 1958 graduate, and reopened in January 2009 after being closed and rebuilding it after a large kitchen fire. The original building dates back to 1956. The hamburgers and the birch beer sure taste the same as the original Royal Castles. The telephone number is 305-MU8-5344.
Update May 2014: Wayne Arnold apparently sold the property to Sean Combs who spent a lot of money fixing up the restaurant and parking lot. Combs re-opened the restaurant on Memorial Day weekend as "Finga Licking" at Royal Castle. That information is from a Miami Herald story based on an Instagram from Sean Combs.
Update May 2017: Wayne Arnold passed away at his home on May 6, 2017. Rest In Peace Thoroughbred Wayne, thank you for years of providing us with those really tasty Royal Castle hamburgers.
