If it's still there (I haven't been to Houston in a few years) Chacho's, at 6006 Westheimer, has awesome Tex-Mex food, especially their fajitas. Actually, all along that street for about 10 blocks or maybe more there are many good restaurants.
The Galleria area itself is mostly about shopping and eating. There is a lot to do and see in the Hermann Park/ Museum district.
