I haven't been for the lunch buffet, but the dinner at Banjara is pretty good! The prices for entrees are reasonable ($9.50 to $12.00). The chicken dishes were tasty, and there were complimentary Papadums.
Waiter was very polite, and the décor is pretty decent. Considering the relative cheapness of the food, I appreciate the nice tableware and linens. Definitely not a bad spot for a 3rd date. Also have some huge tables for groups, so a good bet if you want Indian with your friends.
