This place is a breath of fresh air next to the mediocre international cuisine available on campus. The key to Bamiyan is their impeccable consistency of flavour, the delicious and fresh from the oven naan bread (as a previous reviewer stated, it looks kind of like pizza dough and on first glance looks "processed", but the flavour is there).
I've tried most of the various kabob on offer at this point, and the only time I was disappointed was with their 1/2 chicken. Go for any of the beef dishes and you won't be disappointed.
Prices are also reasonable, and the staff are friendly and helpful. The place is clean but has a mall food court / cafeteria feel to it...but the prices match the decor, cheap!
