Jay Gatsby.

Now there’s a guy who knew how to party.

And nothing bad ever happened to him, so...

Live it up at Gatsby, a stunning, opulent and generally crazy good time of a new Downtown club, now open Fridays and Saturdays on Main Street. (See the slideshow.) 

There’s a lot going on here. For starters:

It’s a 14,000-square-foot, multilevel situation. Which means you’ll have plenty of room to dance and drink among the black bar, gold banquettes and light shows.

They really channel the Gatsby thing. The decor is all 1920s, and even the staff is wearing gold dresses and flapper attire.

Champagne. Just... so much champagne. By the glass. By the bottle. By the dozen. If you’re here, get ready to drink lots of the stuff.

Bring some friends. You know, those select friends who’re always up for dancing, dodging sparklers and celebrating anything, anytime, for any reason.

More is coming. Next month or thereabouts, they’ll debut two more spaces: 1) a downstairs parlor with a separate bar, and 2) a rooftop terrace.

That one’s not downstairs.
