Well, I haven't been there in decades.... the one place I do remember is called The Ponderosa, just of I-Drive (International Drive) near the Wet & Wild waterpark.
They had an All-You-Can-Eat buffet which was amazing and the first time I'd had any proper American style food.
Probably a pretty average chain-restaurant along the lines of Fatty Arbuckles and Frankie & Benny's type places we get nowadays, though.
