The newest addition to 18th Street's dazzling gastronomic block between Guerrero and Valencia (Tartine Bakery, Delfina, Pizzeria Delfina, and the Bi-Rite Grocery, among others) is the irresistible Bi-Rite Creamery. The Creamery offers artisanal, seasonal ice creams, sorbets, and granitas, made in small batches from the highest-quality organic ingredients. The cups, cones, and sundaes are doled out from a freezer counter displaying that day's flavors. Samples will let you know exactly how double ginger, honey lavender, and chai-spiced milk chocolate taste (try before you buy). Novelties of the day might include an ice cream sandwich made with macaroons or ginger snaps, or a pineapple-and-mint popsicle. The snug room, barely bigger than a rich lady's walk-in closet, is lined with prettily wrapped baked goods and other temptations. We're already in love with the tangerine granita and the salted caramel ice cream.
