What kind of places are you looking for? You generally have to head out of the tourist corridor and into Orlando proper to find the good local places.
Just off the top of my head.. some cheap eats: Yellow Dog Eats, Pom Pom's Teahouse, Achilles Art Cafe, Border Grill, Hot Krust, Black Bean Deli
Upscale- Luma on Park, Ravenous Pig, Cask and Larder, K Restaurant, Chatham's Place
