Mr. Frosty, 1470 Garnet Avenue, ☎ (858) 274-9977, [17]. Sun-Thurs 10:30-9:00, Fri. & Sat. 10:30-10. A Pacific Beach institution, Mr. Frostie's has been selling soft serve ice cream since 1949. The simple, no frills menu also includes sandwiches and hot dogs, but it's the dipped ice cream cones, milkshakes, sundaes, and banana splits that will make this place outlast any trendy yogurt shop.
