I was in London recently and entered the Whole Foods shop (I didn't have time to do it when I was in LA and oh how I cried) and OMG. It was like a leafy orgasm. I bought coconut water, beetroot crisps, energy bars made out of cashew butter and guarana and their awesome hemp bag. As well organic banana chips and dried mango. As well as...oh you get the picture. Next time you're in London, LA or NYC do visit them!
P.S They do however sell meat (organic) but hey we can't all be perfect.
