These are in the Dr. Phillips area. Not far at all from WDW and well worth the short (ten minute) trip.
Melting Pot
Too Jay's (for breakfast or lunch)
Roy's
Season's 52 (noisy and not fond of children)
Moonfish
Ruth's Chris Steakhouse
Morton's Steakhouse
If you want to head west, take 192 west to 27 north. There is a little sports pub sort of place in Cagan's Crossings, RJ Gators. It's cheap, filling and fun. (Definitely not gourmet)!
There is a Chili's near there too (across the road). I don't care for Chilis but many folks do.
Bob Evans on west 192 is great for breakfast.
Ale House at 535 and 535 (county and state route) near DTD is another place for cheap, plentiful, decent food. Loads of beer on tap. Another sports place.
If you want to venture further, Rt 50/Colonial Drive in downtown Orlando has a load of wonderful Asian restaurants. Worth the trip!
