Only in NYC indeed.
I'm pretty sure that Artichoke Basille's new NYC location in Chelsea is open until 5am.....with beers, sangria, etc to boot.
Nothing like visiting NYC, going out for happy hour, getting a nap from like 10pm to 1am and then getting up and hitting the streets when the night is in prime time (which is about when Baltimore goes to sleep for the night...lol)
