I take friends and family here quite frequently because I'm vegan, it's close and it offers that sit-down experience that Woodlands lacks.
Unfortunately, they don't mark which items are vegan but your servers can let you know if items have ghee or yogurt in them. Some are more helpful than others, however.
I really like the music and the atmosphere here. Also, they serve your food on banana leaves which I think is super cool. I've eaten a lot of Indian food and I have to say that I think Cafe Krishna has the best Gobi Manchurian in the valley. And it is allegedly vegan, so try it! It is very spicy, however.
