You're in the suburbs -- let's face it -- this isn't a high end grocery store. It was PACKED with customers at noon on a Thursday, mostly the elderly and people (parents or nannies) with small children. It was pretty much a zoo.
However, I was able to find a lot of things for my camping trip -- surprised to find no fewer than three kinds of soy/vegan chorizo (!), tofurky sausages and other excellent treats. The produce section was surprisingly lacking in diversity (and not a lot of good looking organic stuff) but we managed to provision for our short camping trip for less than $40 -- not a bad stop and a great option on your way to the border.
