If you are coming to nyc, and you are looking for Bar and Pub only? Bro, there are many place to visits in NYC during day apart from popular tourists spots. If you want to good bar and pubs, I would say Hooboken, NJ would aslo be good idea, one train stops from Manhattans-there are many good bars and pubs. 

Rent a car and drive on 278/BQE to get 360 view of NYC. If you want to go to beach, Coney Island is cheap and dirty beach. If you prefer better, then go to any beahes on long island area, an hour drive from NYC, you can take train too.

You will enjoy Jackson hegiht also, Firoz Syangden 1974 AD performs in Himalayan Yak, if you want to enjoy it. If you want some nepali grocery, Timor to Jimbhu,  wai wai yo go to nepali grocery in woodside, jackson height.

If you are looking for Nepali girls in pub for many reasons-trust me then won't give you a shit even one works as nanny in long island.

If you just want to drink and wasted- then there are chances you would do very little , coz hangover would not let you enjoy next day moring:-)
