I'd like to recommend India Grille on Jones Road near West Road. They have a great luncheon buffet and the best naan I've ever had! We haven't eaten there for dinner but they have a very large menu.
Pita Express at Hwy. 290 and Hollister is a great little place for lunch. They serve a variety of items on pita ala Subway style. They also have a sampler plate that's good and usually have a Greek item of the day such as pastitzio(sp?). I don't think they're open evenings or weekends.
