Hapa SF

William Pilz's new-school Filipino food truck continues to be one of the most polished. His thumb-size lumpia are always paper-crisp, his chicken adobo tender and glancingly vinegary. These days, Pilz also sells his Sodacraft fruit sodas, naturally fermented, out of the truck. Summer flavors include melon-basil and strawberry-mint lemonade. The best way to track Hapa SF down is to check its Twitter feed.
