Aurora, I have only been toa whole foods a few times in my life (I wanted to see what it was like), I used to car pool with this asian woman who used to call Whole Foods, Whole paycheck and when I visited whole foods I found the prices to be very high.
There isnt a whole foods convient to me so I rarely go there anyway.
However from what I did see, most items did not seem to be kosher anway, the meat for sure not. I cant help you get Kosher Meat, but Empire branded Chicken might be available to you at your local supermarket.
