They have servers, but you have to write your order on a white board and bring it up to the front clerk. I would prefer the server handle this part, but once you order, your food is out within less than ten minutes which is great.
The food was decent - a bit greasy and the butter chicken seemed to be all sauce.
They also use Styrofoam cups, which is why I will not go back. There's no excuse. Use real cups and stop being wasteful!
