We like Bahama Breeze on International Drive. Great Food. Ate there last year when we visited Universal Studios.
What he said!Colombia Restaurant in Celebration.
Charlie's Steakhouse on Universal Dr.
Ruth's Chris on Sand Lk just west of I-4.
If you're looking for both entertainment and food, check into Medieval Times, Pirates Adventure, Arabian Knights and I think there was a mystery one (I want to say Al Capone?). The food is good, not great, but the interactive shows are spectacular and fun!
Sleuths Mystery Diner. Right behind Wet n' Wild. Below average food but lots of fun. Really worth going to.
