2009 will go down in history as the year where the entire city become obsessed with rooftop bars — and there's no reason we should stop now that summer's gone. Whether it's a retractable roof or a serious commitment to space heaters, there are plenty of bars and restaurants committed to keeping their patrons al fresco no matter what the mercury reads. We've rounded up some of our favorite options so that you can stay both well-fed (and well-drunken) and toasty warm.
• Roof on the top of the Wit Hotel is open all year (blizzards? no problem) and has firepits and gaslamps outside to help combat the chill.
• The Dana Hotel's Vertigo Sky Lounge is open year-round, with a bevy of heating lamps and a gas-powered fire pit filled with sparkling crystals.
• When the temperature dips, 90 Miles Cuban Cafe sets out the heat lamps and rolls a roof over their charming patio.
• They close their main patio for the season, but for a special party or large group, Chaise Lounge will open their upstairs cabanas and crank the heat real high.
• Roscoe Village's Village Tap has a year-round heated outdoor area for no-frills beer consumption.
• Head through the main dining/drinking area at Fireside and you'll find yourself in their cute all-season patio.
• Market's beer garden, with its retractable roof and forest of outdoor heaters, is open rain or shine (or sleet or snow or ice).
