Idlicious (Kotbagi Lane, Aundh)
and Do-Say Idlicious (Balewadi Phata, Baner Road)

1. Soul Curry, Katraj Dehu Road Westerly Bypass, half a km towards Dehu Road from Wakad-Hinjewadi cross road.
2. Southern Spice, Dhole Patil Road, Opposite Ruby Hall

Hotel Roopali (FC Road) used to have a good South Indian Thali, in addition to their famous snacks. Need to confirm if they still have it.

Discovered a small Tamil preparation thali place in Rasta peth near KEM in one of galis there. Rs 50, chapati was typical ones you get in the kirana stores, but if you like rice with sambar, rasam and south style veg bhajis, a great place to go for the money.

Heard there is a good udupi style mess too in that location, anyone find it, do update this thread.

For Andhra Thalies, try Andhra Mess at Hinjewadi Phase-1.

Andhra Mess in Hinjewadi is best thali ever
