Key Largo is a restaurant in Old Town Kissimmee, a leisure area with shops, restaurants, and a quite retro/touristy aesthetic that opened in the 80s. This establishment takes its name from Cayo Largo, the northernmost island of the Florida Keys. Famous for fishing, seafood, diving, and the tropical atmosphere.

I haven't found much about the restaurant in my search except for the 1996 postcard thanks to which we can see what the interior and style of the place were like. For now, that satisfies my curiosity, although I will try to keep searching in depth to find better photographs and learn about the menu they offered.
