It is the best place to have south Indian delicious food at very reasona pricel. It is extremly crowded on weekends.
Being a Delhite, we have been regular to this place. We see the same gentlemen at the entrance of the canteen guiding customers for sitting at tables.
The food is typical andhra. The non-veg is reasonable priced having good taste. Take away briyani is very popular. You can have as much food as you want be it rice, puri, sabji etc.
One must visit Andhra Bahawan Canteen!
