"Meh. I've experienced better." is the perfect way to describe Sahara.
The buffet selection is small (about 10 dishes), the Naan wasn't very fresh the day I went, the dessert selection was small, and the quality of food was average.
My friends and I were the only patrons there for lunch on a Wednesday, so maybe the low turnover rate is the reason the Naan wasn't fresh, but now I'm just making excuses for them.
There's nothing distinctively "bad" per se, but I just don't think there's anything "great" or "good" about this place either.
I don't remember the price of the lunch buffet, I suppose like the rest of the buffet it was forgettable (zing!).
I work in this vicinity so I've tried nearly all the Indian buffets in the area, and my vote goes to either "The Host" (not a big selection, but good naan and the food quality is one of the best as far as Indian buffets go) at Square One, or "Tandoori Flame" (A much larger selection, but it is a bit far from this location. Then again who doesn't love long lunches).
If you're just in this area, looking for some good food and enjoy Mexican food, then I'd go right next door to El Sombrero, which is in the same plaza and has some excellent Mexican dishes.
