OLD CITY. Like its stylish sister in Atlantic City, this loungey spot caters to Philadelphia's sexy set (celebs, athletes and veritable who's who of the city's best and brightest) by offering perks like European bottle service, VIP areas, private lockers and world-class DJs. As to the attitude, the state-of-the-art sound system floods the space with über cool house, R&B and hip hop beats, and the lavish decor is punctuated by eerie, iridescent tentacles that extend down from the ceiling, two sleek bars and luxurious furnishing. NB In keeping with the jetsetter vibe, 32° also accepts the Euro.

NORTHERN LIBERTIES. A long-time haunt of hipsters hailing from the Northern Liberties, versatile 700 is a bi-level nightspot that's a great place to gather for drinks after work and an even better place to dance until the lights come on. The club employs first-rate DJs who effortlessly turn each night into a terrific party scene downstairs, one that features great music and a refreshingly laid-back attitude. If you're looking to chill out some, the upstairs lounge is furnished with sofas and all kinds of comfy chairs. Best of all: There's no cover charge.

OLD CITY. This stylish Old City bistro is a cool place to hang out and people-watch, especially at the close of day. The menu features a range of small plates, sandwiches, pizzas, all-day omelets and mains like grilled swordfish, meat loaf and flat iron steak. NB The sidewalk tables are at a premium on days when the weather's cooperative.

OLD CITY. Strutting the streets of old city on weekend nights, fashionable, savvy young professionals bypass the neighboring joints and, without deliberation, stake their space at this cool cocktail bar. A fun variety of concoctions and a spacious contemporary interior explain the spot's appeal, and the DJ's selection of crowd pleasers playing in the background don't hurt either. Should you need to nibble, savory, Asian-inspired bites complement the bar's potions.

CENTER CITY. Exuding style and personality, this urban lounge draws a sophisticated, predominantly gay clientele. Patrons hover over small, chrome tables and sip specialty cocktails from Chocolate Cake (vodka, hazelnut, cream de cacao, vanilla syrup, cocoa) to Sex in the City (vodka, cranberry juice, champagne). DJ tunes keep the bar abuzz, but often the party spills over to the outdoor patio. A full menu features satiating eats such as the stuffed pork loin and grilled vegetable napoleon, and Sunday brunch is spectacular.
