Al Fresco Cocktails at Fog City

Though warm weather can be elusive during the San Francisco summer, Fog City is poised to take advantage of it when it comes. The re-vamped icon is inviting customers to dine and drink al fresco at their outdoor tables lining Battery Street. They're even offering Happy Hour prices and fresh-shucked oysters as an extra enticement. Every weekday from 4:00 to 6:00 p.m., you can chase local oysters on the half-shell ($1.50 each) with a rotating selection of $7 wines on tap, or a summer cocktail. We recommend the Aperol Spritz ($8) with Aperol, Prosecco, seltzer, and orange, or the Kentucky Mule ($7) with Four Roses Bourbon, Fever Tree Ginger Beer, and lime. If the weather refuses to cooperate, come inside to watch your favorite games on the big screen TVs above the bar. 1300 Battery Street

Happy Hour mainstays include the Moscow Mule, the Dark & Stormy, and the John Colins' namesake: a bourbon sour made with fresh orange, lemon, and honey.
