Food trucks are what’s in all over California: A kitchen-on-wheels offers a selection of finger food ranging from hot dogs to curry and oysters. An ever-growing fan base follows these food trucks on twitter and facebook throughout the city, hunting down always changing culinary delights. Not up for the chase? Just go to the SoMa StrEAT Food Park. A dozen food trucks rotate in and out for brunch, lunch, and dinner. The covered seating area and the backyard charm are free.
