Despite the rather warm fall we've been having, we promise, it's eventually going to get chilly. That doesn't mean the outdoor seating you've been enjoying all summer and fall will disappear; thanks to a variety of new-fangled heat lamps, restaurant patrons can extend their alfresco dining days well into the cold weather without risking frostbite. Click through to find restaurants with heated outdoor dining on sidewalks, patios and rooftops.
Continental Mid-Town: The Rittenhouse branch of Stephen Starr's diner concept has a glass-walled rooftop room with a fireplace, a circular bar and a James Bond-meets-Swiss-chalet vibe plus an outdoor rooftop patio with propane space heaters. The third floor is open year round.
1225 Raw Sushi and Sake Lounge: The hidden courtyard at Raw has both heat lamps and tarps. It stays open as long as customers keep asking to sit out there. Management says it was open on New Year's Eve last year.
Rouge: The grande dame of Rittenhouse Square see-and-be-seen dining scene has heat lamps that stay on as long as folks want to sit under them.
Swift Half: The pub has the benefit of being buffeted by winds on all sides, thanks to its location in the Piazza. It also has heat lamps in its patio area, which they'll fire up at a customer's request.
Tria: Tria's Washington Square West location has toasty electric lamps along the 12th Street side of the building. There's no official cut-off date or temperature drop for turning them on or off.
Twenty Manning: The Rittenhouse lounge has both temperature extremes covered - heat lamps for cool weather outdoor dining and water misters for when the summer humidity gets to be unbearable.
Osteria: It's not quite outdoors, but the Italian restaurant has a glass-enclosed side solarium that might be the best thing in really cold weather.
