Hiro is located in the basement of the Maritime Hotel, which is at the lower end of Chelsea on 9th Avenue, with the entrance to Hiro on W16th. It is a popular place on Sunday nights with really good music and a diverse and interesting crowd. Mainly "b-boys" [bartenders, busboys, bouncers and bar-backs as well as designers, hairstylists, and college kids], who don't have to work on Mondays, and those who love them. The crowd gets going after 11p.m. It can get very crowded and you may find yourself dancing between tables.

The music is the draw -- usually deep house -- as well as the swank East (Japan) meets West decor. It is cavernous and looks like you are in an underground warehouse, with cool tables, hanging Japanese lanterns, red decor, an elevated standing table area, and even a sort of upper (VIP-looking) viewing booth with its own bar and comfortable couches.

I don't recall ever paying to get it, but can't say there is no door charge.

Consider the Maritime Hotel roofdeck on Saturday night for visiting djs that are generally pretty good, locals who want a bit of less raucous lounging and occasionally a celebrity spotting. It has a secluded outdoor garden feel that is partially covered with a bar under the cover and benches along the perimeter and lighted planters/trees dotted under the open sky.

Great location, cool vibe, usually a very good time.

Although I was tired of the days in NYC and just wanted to take a look: This place gave me lots of energy and stayed the whole night.
Really good music, nice area, lots of cute and hot guys. Real party atmosphere. And that all for free! (although I am not sure if the entrance is always for free)
This party made it to one of the top-parties I visited!

Wow what a steamy party! Great fun, good music, nice guys. Hot and wild!
