Normally, I shun supermarkets, but I just had to check out the new Safeway in Alameda (which anchors the newly remodelled "Alameda Town Centre" (aka South Shore shopping center) and replaces the really horrible Safeway in that center).
It's huge. I mean, really huge. Probably the biggest grocery store I've ever seen (that is, that sells primarily grocery store items, not a combination grocery/drug store, although it does have a bank, a pharmacy and a Starbucks). It also has a much more upscale atmosphere than the average Safeway -- more like an Andronico's. This is exemplified by the fact that one entrance is dominated by "gourmet" items, a huge prepared food area and a wine department with an impressive selection of wines, including premium lines: practically the first thing I saw when I walked in was a display of Stag's Leap Wine Cellars Artemis Cabernet Sauvignon, at about $36/bottle (suggested retail $50). I didn't count, but estimated there were between 50 and 100 California cabs alone. Large produce section as well, with a decent selection of organics (a sign with updatable numbers announced they had 57 organic items in stock "today").
I don't think I'll be abandoning my anti-supermarket shopping philosophy, but I'll probably hit it up occasionally, especially since it's open 24 hours. Mostly I imagine I'll still shop at the Trader Joe's next door (where the clerk said they're busier than ever since the Safeway opened).
