I used to shop here with my mom a lot. Recently, I've switched over to a local independent health food store. Whole Foods is good for introducing people to organic/natural foods, but over all, it seems as though they value quantity over quality.
While they have a huge selection (produce, groceries, body products, etc...), a lot of it is just conventional stuff you could find in any supermarket. It seems like a lot of upper class snobs and yuppies have gravitated towards shopping at Whole Foods because it's in vogue. It's great that organic is becoming more popular, but unfortunately in a place like WF, the quality has to be sacrificed to meet the demand. (On a side note: I hate walking around Whole Foods in the winter, seeing all these rich women walking around in their real fur coats. It's disgusting).
From a Vegan perspective, Whole Foods is a danger zone. Yes, they have your basic vegan options. But beware of the prepared food sections. They often label things "Vegan" but when you look into the ingredients, you'll find they use dairy products (butter or yogurt). Apparently, they aren't well informed about Veganism. This was a real disappointment.
On top of everything, Whole Foods is pretty expensive. You'd thing with such a huge stock, their prices would go down a bit. But I can buy cheaper stuff at my local natural foods store. So, if you're thinking about shopping at this Whole Foods (or any WF, for that matter), try finding an independent natural foods store near you first. If WF is your best option, go for it... but shop with care.
Cons: sells a lot of meat, expensive
