There are two importatnt things you look for , when you visit Tirumala next time.
1. While entering the main entrance ( after the baggage checking)- Mahadwaram - to your right you see a crow bar ( gadapparai) hanging on the wall, with the sign - " Anandalwan, gadapparai)
2. Next in the south mada street ( before the foot overbridge) under a Maghizha tree, to your left, the Anandalwar sannidhi.
