Not a comprehensive grocery store, but a great place to go when you need high quality ingredients or perhaps some special premade item in the frozen food section. Gourmet (sort of) quality at cheap prices. High-quality cheap wine, as well (can't beat the two-buck Chuck). More of a place to search and find new things than to find what you're looking for.
Pros: Good food at good prices, interesting shopping hunts
Cons: Very busy on weekends and evenings. not a really wide selection
