The lunch buffet is your best bet. Otherwise, each entree rather expensive. Provided that you attend the lunch buffet, self control is imperative. However, if this is unavoidable, be sure to wear trousers that are loose, although garments with an elastic waist band, such as sweat pants, would suffice. Leggings are not really pants.
I've been coming here for close to 6 years now and have recently introduced boyfriend to the mango lassis. They're not really authentic (according to my Indian friends - I don't really have any authority on this) but super good.
