One of the most infamous "mob" restaurants was located in Ft. Lauderdale, Sonken's Gold Coast Restaurant owned by Joe Sonken, who was very close to the Chicago Outfit. The restaurant served as a meeting place for messages throughout the years between "many" of the families across the U.S.

I lived in Jupiter for 6 years in the early 2000's and ran into John "No Nose" Difronzo from Chicago at a place in Palm Beach Gardewns called Carmine's. Make a long story short, Carmine Giardini, restauranteur and upscale grocery stores, was stabbed a few weeks later in the parking lot of his restaurant. Ironically, it was an off duty cop that came in from Chicago. I remember being a bit puzzled as to the timing of DiFronzo in South Florida and the stabbing that took place shortly after. Don't think there was a connection, but Carmine supposedly borrowed money from some other mob connected guys for some of his expansion in South Florida.
