Breh it's 70 city blocks north to south, and 3 long as city blocks west/east. On the subway is like 6 stops which is roughly ten minutes. Now imagine trying to walk that motherfukka, lol.
Honestly breh, depending on where the location of the wedding is, it would be easier to give locations to hit up. Manhattan, you can hit up the East Village, Midtown, the Lower East Side, Tribeca, Harlem.
Stay away from Chelsea & Greenwich Village, that's where the homos roam.
Studio City & Williamsburg in Brooklyn is also a couple of good spots. Astoria in Queens too.
