I've been here for the buffet four times in the past 2 months, and I will be back. My only real complaint is that the food on the buffet is never hot (temperature). Every time I've been, the buffet has different options. The red fried gobi is great, as well as the saag and other gravies. The Chinese noodles were spicy! The buffet naan is typically stale, but they are happy to bring fresh naan to your table if you ask nicely.
Home cooked Indian food is by far superior, but I don't have high expectations for buffets, so Tulips works for me.
