I go to NORA cupcake more than I should. Their cupcakes are amazingly good. Usually there are between 1 -3 vegan choices each day. It's best to call ahead because they often sell out of the vegan ones. They are expensive, but worth it for a once in a while treat. If you want to hang out there they have an interesting room to the side with lots of seating.
Cons: only a few choices, expensive, sells out of vegan choices sometimes
