Best bar hopping (ie: packed with most number of different bars) streets in Manhattan?

I am looking for the best streets to bar hop for the different neighborhoods in Manhattan. What I am specifically looking for are streets in different neighborhoods that are just packed with bars one after another (ie: the streets with the most number of bars packed together within walking distance). I live in East Village, so have found Avenue A as a good street with lots of different bars to hop around, but am looking for different neighborhoods in Manhattan.

Looking for suggestions for the following neighborhoods: Gramercy, Chelsea, West Village, Greenwich, LES, Soho, Tribeca, Financial District

NOTE: Before anyone flames me or downvotes, please know I have tried to do due diligence myself and have explored other areas/streets in the aforementioned neighborhoods. However, when friends/I go out there, we generally find the one bar we were going to, and then are wandering around looking for others, we end up in no mans land with nothing around. I am not looking for isolated bars, I am looking for the most busy streets where as many of these bars are lined up that we can quickly hop to. Hope that makes sense. Thanks in advance!
