I first went to Doughnut Plant in 2007, where I had a lavender doughnut--how unique! On this trip, I went twice, and pigged out on hazelnut, meyer lemon, vanilla bean, coconut, and creme brulé doughnuts--oh my! Plus, they make a mean chai! You really need to check them out. As a bonus, they are really, really nice.
