It's is an amazing lounge for u to go with ur friends. I new to Pune and was finding a place at midnight with my friends from Mumbai n coincidentally landed at co2. An amazing grafitissed ambience. Has an American bar concept, with snooker n 9 ball tables with a sports bar which serves beer to scotch. Good music, with an in-house DJ GAGS. My friends were taken aback n were surprised to c a lounge like this in Pune n for sure when they come to Pune they will be meeting me at CO2.
