I echo some of the other reviewers by saying that this is my favorite Indian restaurant in Vegas. I don't usually like to go to the strip to eat, unless it's a special occasion, but Tamba is worth it. It is very upscale in decor, yet has good ethnic flavor to it as well. Waiters are attentive, but not overly so (which I hate).
The buffet choices are excellent and all food is fresh and warm and tasty!
The only drawback...it is closed for a couple of hours before dinner time (I belive 5:30PM or so?) I like my dinner early sometimes, and it was a bid of a disappintement.
Overall, recommended. Very clean place.
