I don't get all the negativity.. the OP is thinking smart. A great place to meet women is a spot where they're not ready for it.. you catch them off guard.
It makes sense that a lot of attractive women are at Whole Foods. Think of it this way:
To shop there... you are showing a concern for the environment/ fair trade economy. This is a sign of being active in the world, and thinking about their lives a bit (anti lazy if you will). These types of women will traditionally care more about their body, what they wear, and generally be more interesting to talk to, as they are passionate about something (so just act like you give a shit about the environment for two seconds.. maybe drop that you tried going vegetarian for a bit too if you're real ballsy). You as the lucky gentleman meeting them there appear equally as attractive.. because you are showing a concern for what you eat and where it came from/who grew it, and don't mind paying a little extra to support what you feel is right. The hard part is having the confidence to strike up a conversation, as always, but keep in mind that whatever game you spit there, will probably work better than at a bar.. if you're hoping to meet girls of this calibre. It's stupid how easily girls fall for guys who are passionate about the same things as them. They see them as someone worth getting to know.. not some Arthur Kade-esque clubbing douche who's not talkin to 6's.
But if you go to Whole Foods to simply oggle them...well then that makes me sad.
I suggest going to an independent meat market.. then you can still find the same types of people concerned with supporting the locals.. except they aren't hippies, they're women who have barbeques, and meat to grill. God I love butcher shops.
