Blue Martini at Millenia Mall is pretty cool if you like to mingle with the "Beautiful people of Orlando", it's not too expensive and it used to be the place where the infamous/famous Tiger Woods used to go to pick up hot chicks.
Universal's City Walk is OK if you don't mind sharing your space with sweaty tourist in shorts. I do find the restaurants there usually over priced and not so great...
There is a pretty cool place downtown on Church's Street called Ceviche (
http://www.ceviche.com/) great food, live music on week ends, plus it is right in the middle of the action, so once you are done eating you can check out all the bars and clubs around.
If you have anything specific you like to eat, let me know and I can direct you to some other places...
