Diya RestaurantMy husband and I had lunchMy husband and I had lunch at diya! We both loved it..that was the second time we tried their lunch buffet and it was outstanding!! What I liked the most about this restaurant is that they change the food selections at the buffet. Also, the best masala cai I've tried so far.. Service was friendly and attentive!! We will be back!3/14/2013 12:00:00 AMWaitstaff is very polite andWaitstaff is very polite and friendly but somewhat rough around the edges when placing food items on the dining table. Wouldn't expect this finding in a restaurant at this location.(Tysons).3/14/2013 12:00:00 AM
