We go to Persis Biryani once a week on average. The food is that good! I'm giving this one star tonight however. I recommend perhaps not going here on a Tuesday night. The food while delicious as usual came to us via perhaps the worst service we experienced since Persis opened in the University City area. Usually the restaurant is slammed and the table service is amazing...tonight they were slow and both the table service and friendliness of the staff earned a D minus.
