Been a few times. Indian food in the main touristy area. Obviously you pay more than Vietnamese food (110k for a thali, 80-100k for a main, roughly). It was definitely not up to British standards of a great curry but it was tasty enough and quenched my need for Indian food. The mutton roganjosh and garlic naan were the highlights. They served the food with about 5 chutneys which was a nice touch and you let a mini rice pudding at the end which is tasty.
