Andhra Pradesh Bhavan (or AP Bhavan), as the name suggests, offers traditional dishes from the state of Andhra Pradesh. AP Bhavan is absolutely packed on weekends with lines of 100+ people waiting for an authentic taste of thalis and biryani. The space is more like a canteen instead of restaurant and an unlimited thali will cost under $2/person. Biryani is served on Sundays, but visit by noon. There is very little elbow room past 1pm.
