I'm not saying most of the posted places aren't good, but they're rather ordinary. I can go to most of them in my backyard.
Try Cafe Tutu Tango on I-Drive. They serve an unusual menu of appetizer sized portion intended for all in your party to share. You order a few, eat,order a couple more,etc. Great food and fun & the restaurant is also a "starving artist" type location. Very interesting.
Over on Sand Lake road almost across from the Publix is a Melting Pot. They are a chain restaurant, but not that common. It's a fondue eatery.
Back on I-Drive, in I believe the Holiday Inn is the Shogun. It's similar to Tapenyakki's in Epcot, only much more reasonably priced. Stop at one of the tourist centers and pick up a coupon booklet. You'll probably find a buy-one,get-one coupon coupon.
If you enjoy seafood, try The Boston Lobster Feast. It's an all-you-can-eat buffet that includes unlimited whole lobsters. It's about $26.95 pp. It includes raw oysters which I LOVE, steamers,u-peel shrimp,sushi bar,crab legs and a host of others.
Have fun.
