Whether you prefer yours shaken, stirred, dirty or garnished with a twist of lemon, Philadelphia’s bars offer a diverse array of the classic cocktail. Check out some of Drink Philly’s favorites below. And if you know of one that should be included, give us a shout on Facebook or Twitter.

Franklin Mortgage & Investment Company (112 S. 18th St.; 267-467-3277)
