Add pies to the list of underground street foods you can score form a cart in the Mission. Place? Dolores Park. Time? Just about 30 minutes from now. New vendor Bike Basket Pies is promising to hawk strawberry-rhubarb, blueberry-mango-coconut, and mixed berry mini pies, with a nod to the neighborhood's à la mode lovers: via tweet, BBP suggested he settled on today's late afternoon debut to let buyers swing by Bi-Rite Creamery, "so you can hit your ice cream fix too." Thanks to Mission Mission
for pouncing first.
