I grew up in Burlingame, and have family in the Bay Area still. Whenever we are headed back to New York, before we return the rental car at the airport, we like to eat lunch, or pick up snacks, at a couple of our favorite places. They couldn't be more different from each other.
Earthbeam: it's the health food store I grew up going to--perfect for healthy snacks (1399 Broadway in Burlingame)
In-N-Out: So insanely good...11 Rollins Rd. in Millbrae
