This is hands down the best new fast food place I have been to. They take the PeiWei approach where you order at a counter and wait staff bring your food to the table. The food, however, is much better quality. The bill it as "Indian food redefined." I've had the Biriyani, spicy Tandoori, and the Kadai--all were excellent. Lunch entrees are around $10 and you can easily get in and out in half an hour making it a great workday lunch place. If you like Indian/Asian-influenced food definitely give this place a try.
