My one piece of advice to anybody who visits NY is: bring walking shoes, even if only as a courtesy to your host so they don't have to deal with you whining about your sore feet. If you're slapping around in your flipflops or your fancy shoes you bought at Diesel or H&M or some other piece of shit store because you're more concerned with looking "cool," I will have no sympathy for you. It's NY; people fucking walk.
