Best place (IMHO) is 16th ave / 50th street, in front of Nicholsberg. Crowd is great(chilled, but not too tzelos’t)and its starts about an hour after the zman
Mechuel Shnitzler was there last year, and he gets the place hopping!
And for all you litvaks: As soon as you’re within a 50ft radius of anything chassidish (BP, CH, Willy, ect), its on our dime, so relax and join the fun!
