Dropped by during a trip to San Diego just to check it out and was a bit disappointed. Nothing to write home about really. It's kind of between a Whole Foods and a regular grocery store, more to the latter. No salad bars/cafe where you can sit and chow and didn't seem to have as many local products as WF, but at least they have a decent sized bulk section in case you need to stock up.
P.S. It changed its name to "Sprouts" apparently because of a merger.
