Ah yelp, you should allow half stars. I would rather give this 3.5 stars, so I opted to go lower instead of higher.
I love indian food and having several vegetarian/vegan friends, we tend to go out for it quite a bit. I love seeing the variations between all the different places.
Delhi Darbar is a nice quiet place on 16th. I have never seen the place packed, but it definitely has some of the best food in the city. I've never been to the buffet, but I've had dinner here a few times and it's always delicious. I highly recommend trying it!
That being said, last time I was here, the service was really slow and it did take awhile for the food to come out. I think service could use a little more attentiveness and it would go up in the rating.
