Attico
The Cambria Hotel's sleek, chic rooftop bar offers panoramic views of the city and is open year round, thanks to clever tenting and a cozy indoor space where you can still hang out during the coldest months of the year. (219 South Broad St Rooftop; 267-536-5725)

Irwin’s
Head to the top of the Bok building during the winter when Bok Bar is closed and hunker down at Irwin's, a homey space that looks like your dream living room and serves up creative cocktails to boot.

Parc
One of Stephen Starr's most famous restaurants, Parc perfectly mimics a Parisian bistro right in the center of Rittenhouse Square — sidle up to the enormous bar or grab a table by the window, and you'll think you're on the Left Bank. (227 S 18th St.; 215-545-2262)

Mission Taqueria
Situated atop its sister restaurant, Oyster House, Mission Taqueria's wide windows and skylights make it the perfect place to celebrate Taco Tuesday, share a plate of nachos, or sip a green juice margarita (all of Mission's margaritas are made with fresh juices squeezed right then and there).

Tria Café Wash West
Philly's premier wine bar has two locations, but thanks to huge windows throughout the whole space, Tria Café's sunniest location by a long shot is its outpost at 12th and Spruce, where you can pair the perfect wine and cheese in bright sunshine any time of year. (1137 Spruce St.; 215-629-9200)

Bar 210
Even if you're not splurging on one of the city's best prix-fixe dinners or brunches at Lacroix, you can still visit their bar any time you'd like and enjoy a sunlit cocktail or glass of wine at the cozy bar. Grab a seat during the winter and look out at Rittenhouse Square (and if the weather is really cold, Bar 210 is a great spot to watch the snow fall). (210 W Rittenhouse Square; 215-790-2533)

Mainstay Independent at Craft Hall
The original Yards Brewing location has been transformed into a family-friendly food hall called Craft Hall, which is also home to Mainstay Independent Brewing Co., another worthy addition to the Philadelphia craft beer scene. Try one of Mainstay's signature brews in their bright space, which even has a fireplace for really chilly days. (901 N Delaware Ave.; 215-422-3561)
