Simmering in the city? Grab a cold one at these seasonal cocktail patios coast to coast. New York’s Patroon (160 E. 46th St., 212-883-7373), where you can toast the Midtown surrounds with the house gin-apricot-citrus Patroon Punch, reopens its rooftop terrace after a years-long hiatus. In Chicago, Keefer’s (20 W. Kinzie, 312-467-9525) freshly debuted sidewalk cafe serves signature Sorbetinis — vodka and sorbet freezes in peach, grapefruit, cherry, apple, and orange flavors. And in San Francisco, when the fog lets up, sit down on the patio of Eastside West (3154 Fillmore St., 415-885-4000) for a red grapefruit daiquiri.
