Visited Goa in Oct 2012 and went to Tittos, the most overhyped place. They charge you Rs 1500, however its just not worth it. The Drinks are fake. Juices , they only have orange juice (Real Brand).
The quality of vodka is very cheap. My friends had and they were actually felt like puking. If you really wanna drink the safer bet is the Beer. Its very congested and the floor is too small.
