Off the Grid is a bus that goes nowehere, but serves burgers and barbecue out of one half and beer and cocktails out of the other.  Seating is outdoor and dog friendly.  There's also a taco and burrito truck in the parking area to choose from.

<AH> Great place and vibe (kind of a hippie outdoor chic).  The burgers and sandwiches are ENOURMOUS so buyer beware.  </AH>
