I went here my first night in Pittsburgh and didn't really return until the past few months. Suddenly, senioritis plus having a car at school = a late night excursion every week. I still feel the same way about the food, it's good and it's satisfying (but nothing to write home about). The price, however, is so much better. During half-price you can get chicken or vegetarian entrees for half-off.
My favorites dishes include Chicken Saag, Chicken Makhani, and Chicken Tikka Masala. They also do a decent garlic naan.
The only really new thing to say is that I've realized that the service could use some improvement, which is disappointing when you go there every week. There was one time I ordered Chicken Saag and it came with literally two pieces of chicken. It was awkward explaining that this was wrong; same with the time I went with Hao S. and they gave us a dish of rice that was considerably smaller than the last ten times we ate there. Being a regular doesn't really get you much at this place. The waiters won't even hide the fact that they want to try to bustle you out as soon as possible so they can close-up; they have zero interest in even pretending to be interested or friendly the way that most people would in order to make a decent tip.
