The last two weekends there's been pozole available in the take-out, soup area of the Whole Foods on 4th and Harrison. I tried it on a whim and the pozole is seriously good. It's a red pozole, not white, and it is quite spicy. The hominy is perfect and has a purple hue. The only odd thing, or I guess Whole Food-ish thing, is that it is made with chunks of chicken as a opposed to pork. The condiments for pozole are missing though, so there's no oregano, raw onion, lettuce, limes or tostadas to accompany the dish. For $3.99 the small portion is worth a try if you are in the neighborhood and want pozole.
My only other non-homemadel pozole experience was the white pozole at the Alemany Farmer's Market stand (name escapes me) a year ago and it was bland and boring.
