This place is really a distributor of food with a restaurant next door, under the same ownership. It's always bustling with lots of people ordering food, from the variety of regional cuisine dishes (Northern and Southern foods), drinks (try the Maaza) and desserts (try their Gulab Jamun!).
The food is cheap, but that's because it's self-serve. You order, and you wait for your food to come out. There are barely any places to sit, so often times you have to eat at a standing table or just eat standing.
The food is authentic, and hence lots of Indian people come here to eat. Most of their entrees are really spicy, so drink lots of water, or get a mango lassi to accompany your food.
