There's quite a few restaurants in the Houston area. and now time for Kam answer. Duhh. Olive Garden. You know, Bennigans.
Vic & Anthony's. If you're fine with a $30 price point you aren't getting better food. Be sure and get 2-3 crab cake appetizers and a portobello mushroom appetizer to share.
hmmm....like a birthday party or a cool place to hangout? Pesce seafood is quite good. Vic and Anthony for steak My new favorite is Boiling Crab. Place is freakin awesome!
Ninfa's on Navigation has become my go-to place for out of town guests, and just about any other occasion.
Ninfa's on Nav is a good call for tex-mex. For steak, as others have mentioned you can't beat Vic and Anthony's, but you're likely to spend over $30 a plate there. Hugo's is a good spot serving upscale Mexican fare and it falls within your price range.
Dave and Buster's!! $10-$20 plates, pool, shuffleboard, 2 bars, and some games if you're into that stuff too. Plenty of tv's as well. Pappasito's is the closest mexican restaurant I can think of to that price. I think Doneraki is pretty expensive, although I've never been there. Can never go wrong with Chuy's!!! Not sure how much it is, but Houston's is supposed to be a good (expensive) restaurant as well. Pugs
I tried DaMarco's based on someone's recommendation on this message board and it was the best food I have ever eaten. Was more like $50 a plate, though...but holy **** was it worth it.
da marcos is the best restaurant in houston, imo, but can and often will run you well past $50 per person.
