Shiv Sagar on J M road is one of the best places to have Pav Bhaaji.
Variety of Pav Bhaaji is available -
Standard Pav Bhaaji
Paneer Pav Bhaaji
Cheese Pav Bhaaji
Rates are also pretty ok. Standard pav bhaaji starts at 42 Rs, and I think it goes upto 65 for the Cheese Pav Bhaaji.
Another favourite dish I like at SS is the Paper Masala Dosa.
South Indian cuisine is also good. It is one of the most crowded places in Pune and has a waiting of almost 10-15 mins in the evenings.
