I have been to the lunch buffet a few times, and although it's a couple dollars more than other places (Tiffin Wallah is only $6), I feel the food is higher quality and there are a couple more options. I also really like that they bring you a dish with these sort of Indian-style breadsticks, which are delicious.
While the food was really good, and the waiters were friendly, on my last visit here, I thought the man ringing my friend and me up was rude. He was acting as though they didn't have any change if we paid with a $20 (not a huge bill), so we thought he was just trying to keep an extra $5 for himself for a tip. I've never seen this happen here before so it may not happen on a regular basis.
