Don't be scared off by the line that snakes out the door, down the stairs and around the corner - this means the food is amazing (and it's worth the wait).
If the wait is not your thing (you'll wait a bit even if you have a reservation), order takeout, and you'll be in and out in just a few minutes flat.
Order the chana samosa, baighan bharta, and the shahi paneer (these are all my favourites). It's hard to go wrong, though, so peruse the menu until you find something that strikes your fancy.
Go at lunch to take advantage of the $5 vegetarian thali. Pair it with a mango lassi and you've got a stellar meal.
This is a hole in the wall spot so don't expect linen tablecloths and a fine dining experience. What you'll get instead is great food, a friendly server and some stellar people-watching moments.
BYOW.
