I'll add a few more that I don't think I've seen on here yet. I'll stick to local, non-chain Orlando restaurants since I've seen requests for those:
Coq au Vin (French, wins best French every year from both the Orlando Sentinel critic and the readers)
Red Bamboo (Thai, at Kirkman and I-Drive right near Sweet Tomatoes)
Blackwater BBQ (Excellent ribs, located off Orange avenue just north of Coq au Vin)
Dessert Lady (at the corner of Kirkman and Conroy)
San Jose (Mexican, off Colonial/50 right near Hiawassee)
Yellow Dog Eats (good little sandwich shop in Gotha - Google for directions, there's no easy way to explain

)
Goodfella's (Italian, over near UCF - the rolls are great if you love tons of garlic)
Fuji Sushi II (At Conroy and Hiawassee, not too far from Universal)
G&G Thai (same plaza as Fuji)
Amigo's (off I-Drive and technically is a chain, but it's a local chain)
AAshirwad Indian Cuisine (also right near Sweet Tomatoes)
Bill Wong's Super Buffet (Chinese buffet, right at Kirkman and I-Drive, DH loves this place)
