If you want something a little less "chainey" for dinner, try some of the restaurants in Celebration. They are located in a very cute little town center type setting and the two restaurants we tried, we were very impressed with.
The first one was Cafe D'Antonia which was, of course, Italian. They have a wood-fired oven on the premises and I understand the pizzas a very good. The other dishes (Chicken Piccata, Eggplant, etc.) were VERY, VERY good. It's like a miniature version of Carraba's but the food was actually much better.
The second restaurant we went to was the New Market Cafe which was diner style. The ambiance was pretty nice for a "diner" and the menu selection was extremely varied. Something for everyone. My parents got soup and salad, one of our party wasn't hungry and just got soup, my son got Beef Stroganoff (very good but heavy for July!), I got Open Faced Turkey Sandwich with Mashed Potatoes, and my DD got Fish and Chips (very good fish). They supposedly have a tuna salad that is one of the best (didn't get to try it on this trip). They have so much more. The best is that they have homemade pies and the Banana Cream was very good. I wish I hadn't run out of nights in Orlando as I would have gone back to try more.
The diner was very affordable. The Italian restaurant a bit pricier. There were two or three other restaurants there also that get good reviews. I think you should try it if you want something unique and not what you can get at any other town in the U.S. I guess I'm just weird that way, I hate to go away and eat at the same restaurants that are 5 miles from my home.
