Trader Joe's carries a lot of specialty and organic items similar to Whole Foods, but the prices are much more reasonable.  Trader Joe's is also ideal for a single person or people who don't cook elaborate meals.  There are many prepared meals and snacks and most are healthy.
The staff here are also refreshingly friendly, in a next-door-neighbor-where-there-are-no-property-rights-issues kind of way.
Additionally, the selection of wine--inexpensive and still tasty--is phenomenal.  My wine pick: Rene Barbier (?) Mediterranean Red.  I believe it is less than $5 and is so juicy it pairs well with almost anything.
