I come here relatively often, usually bringing friends that have never tried Indian food, or just for the buffet. I will say that the service in general isn't as good as it was a few years ago, however it has also gotten better recently. There also aren't really many other nearby Indian restaurants.
The butter chicken here is very good, and the naan is always made perfectly. The chickpea curry is made very well here, and goes very well with the naan. I don't order food too often except for butter chicken or lamb tikka.
The gulab Jamun and the Jalebi here is always worth getting as well!
