I just recently had my fourth visit to India Gate for the lunch buffet. I must say the place has grown on me. The selection is large and the food is hot and fresh. The lineup changes often for the buffet but usually consists of a couple curries, masala, a chickpea dish and maybe some goat (which I have yet to try)and rice pudding for dessert. Service isn't always very friendly or outgoing, but it's all very functional and efficient. Naan is refilled quickly and regularly as are the drinks.
Take time to enjoy the jamming Indian music that is played. You might catch yourself doing some toe tapping. India Gate is a great place for lunch if you want to give Indian cuisine a try or if you're a regular. I highly recommend.
