SOUTH END. A lounge that transcends cool, 28's wins high marks thanks to its suave atmosphere, inventive cuisine and superb cocktails. Indeed, whether it's to indulge in tuna tartare, to savor a key lime martini (the lounge, after all, is named after the optimal chilling temperature for martinis), or to listen to the hip soundtrack assembled by that night's DJ, this South Ender is the type of place where hip, young urbanites hold sway. Aesthetically, the space features basic black and white walls, dim lighting and soft, comfortable banquettes.

BACK BAY. While glitz and glam are terms that don't necessarily apply in Boston like they do in a city like, say, New York, there are a few establishments in the former that cater to the discriminating patron's palate. This handsome restaurant and lounge is just such a place, combing sophisticated design elements (LED-lit bars and stairwells, maple ceilings, and weathered brick walls) with fine New American cuisine. True hipsters, though, brush past the folks gathered at the bar or seated in the restaurant and make their way down the stairs to the suave lounge area, where celeb DJs and deep-pocketed VIPs hold sway. NB Tables in the lounge are by reservation only.

BACK BAY. This restaurant-lounge captures the true spirit and style of Spain, from the easy-going air to the colorful art to the intoxicating music. Not just a pretty scene, BarLola also sees to discriminating palates' tastes for "tapas y vino." Indeed, small cold and hot plates like mixed olives with Canary Island dressing and Andalucian braised lamb, respectively, dominate the menu. Meanwhile, the wine list is composed of hand-selected Spanish vintages, and their sangria is legendary. What's more, the signature elixir, the Lolita (Stoli Perik, Gran Torres and mango juice), is as potently delish as they come.
