Notes: Amazing, extremely vegan friendly Indian restaurant in Clear Lake. They offer a lunch buffet that's great, and they'll happily point out the items containing dairy. If you order off the menu, get them to veganize the Vegetable Korma. Warning: rice contains butter.

Notes: They are really nice about pointing out which items in the buffet don't contain ghee (clarified butter). On the menu, the Gobi Manchurian is what you need.
