Concept: The sort of place one might expect to find Alice in Wonderland’s raunchier, rowdier older sis, this nightclub–art gallery–amusement park is the brainchild of former NYC impresario Peter Gatien. And with a capacity of 2,800, four storeys and nine theme areas, there’s no dearth of eye candy. Created to look like a giant lavatory, level one’s Washroom Bar is en route to a display case housing recently separated Siamese twins (fake), a motorcycle (real) and a giant tarantula (fake). Move upstairs to inspect a soundproof screening room (3-D glasses provided), a touch-sensitive bar and booth (patrons’ imprints light up on anything they handle), and a shrine to New York pop art sensation Kidrobot.

Crowd: In the weeks since its opening, Circa has hosted shiny scenesters, sweaty club kids, the usual 905 contingent, and a handful of curious Bay Street boys looking to blow off steam. An odd mix, perhaps, but it all irons out on the dance floor, where pulsing house music makes for a shimmy-worthy—if deafening—soundtrack.

Cocktails: So far, most of the magic is going on around the many bars, not behind them. Word is signature bevvies are in the making, but for now high rollers can rent real estate at one of 20 private bottle-service booths, where the cocktails are as imaginative (and twice as expensive) as you want them to be.

Circa, 126 John St., 416-979-0044. Friday and Saturday 10 p.m. to 4 a.m.
