From the outside, Roberta's looks like a squatter's paradise. But step inside, Narnia-like, and you've entered wonderful world of red sauce, wood-fired pizza, and cute pixie-cut hostesses. Oh, and one of the best, hippest pizza spots in NYC will also play host — in partnership with our friends at Cole Haan — to two of the swe-etest outdoor DJ all-day dance parties in Brooklyn (held in the lovably ramshackle backyard). Enter: Tiki Disco on Sunday, September 2 and Sunday, September 16 (from 2 to 9 p.m.), with get-off-your-feet soundtracks by resident DJs EliEscobar, Andy Pry, and Lloydski. (Oh, and If pies and sweaty, sweaty dancing aren’t your speed, try Blanca, the sleek, 12-seat tasting-menu-driven space Roberta’s owners just opened up behind the O.G.)

For Roberta's, we suggest you wear something loose, stretchy, and cute — you're going to need a forgiving ensemble what with all those delicious pies, cheap drinks, and backyard dancing. Dress it up with a comfy heel, a high- impact, bright carryall, and conversation-worthy jewelry so you don't look like you're wearing a big T-shirt (which you totally, totally are.) Head to the Cole Haan #DontGoHome Facebook tab for your change to grab a seat at the table. We already did.
