As someone who used to be vegan and vegetarian at various points it was refreshing to be able to pick anything off the buffet without having to worry (especially if you're new to Indian food). When they are busy sometimes you don't get your glass refilled as much and sometimes when you ask questions there is some language barrier. I enjoy eating here and have mentioned it to vegetarians I know who live farther away than I (its a bit of a drive) that it is worth the trip if you like mildly spicy Indian food. My husband does not have a hard time finding things to eat either (he's always been a meat eater).
Pros: All vegetarian, buffet usually has a lot of choices
Cons: Sometimes language barrier and sometimes service
