For shopping: WF has great vegan meats, cheeses and other vegan specialties like vegan pudding and yogurt. Also carries FAIR TRADE bananas (hard to find). They have the kid-size shopping carts, too, which makes shopping with littles easier.
For dining: The salad, soup, and hot food bar have plenty for vegans and everything is clearly marked. You can also order a vegan pizza custom made to eat there or take home. The bakery often has vegan cookies, bread, and there are usually some raw vegan pie slices and sorbet too.
