We have Bahama Breeze here in Atlanta and would definitely second that recommendation.
If you like Chicago style pizza go to pizzeria Uno at the Crossroads. I love their pizza but the rest of the family can't stand it.
We love the diner at Celebration (don't remember the name, but it's on the corner across from the lake). They have great meals and awesome desserts. Celebration is a nice little place to walk around too.
