Johnny Doughnuts is the go-to place if you have a sweet tooth and have been lucky enough to enjoy a handcrafted offering from one of their food trucks at another location in the Bay area. They offer organic coffee and teas to accompany everything from a classic raised doughnut to caramelized apple fritters, wild-berry-jam-filled bismarks, and "crodoughs," a delicious creation of a croissant crossed with a doughnut!
