The Outside Lands music festival, coming to Golden Gate Park’s Polo Fields and Hellman Hollow this weekend, is known for eclectic acts. New to the food programming this year is the Snack Series, a way for participating kitchens to offer half portions of some dishes, all for less than $16. While we’re on sandwiches, A16 will be serving up veggie paninos for $16, and bagel chain Wise Sons is teaming up with darling Outta Sight Pizza for a pizza bagel, also $16. Great for groups and wallet positive, think of this dish as a briny, salty plate of nachos. Or, for $16, you can sip on Arquet’s New England style clam chowder as if it were a martini.
