My husband and I had the lamb saag and chicken korma. Both were excellent, super flavorful and rich tasting. Wait staff seemed familiar with GF and said that those dishes were GF (as they should be). Skip the naan and you should be fine. The restaurant was clean; the place was actively being wiped down, etc. I felt comfortable here GF-wise and cleanliness-wise. I would definitely eat here again.
I eat here frequently. If you don't eat the naan, it all seems GF, and it is all delicious. I have always just eaten the buffet. I love the saag paneer. There's also a very good okra curry that I wish they had every day, but I only see it once in a while. Best Indian food here locally!
Most gluten free people know that if there is a language barrier at a restaurant, it's probably not good to eat there. This place however has never gotten me sick! The waiters can tell you what does and doesn't contain wheat and most of the food is already gluten free!
