The Red Verde is an amazing place. It's 100% vegan, which is great, and I always found there a very kind girl ready to clarify things about products in the shop. They also sell vegetables and fruit.
Although the place is by no means big, there are many interesting products and I sometimes bought things I didn't know just for the sake of trying. In any case, you end up with something vegan, so there's no risk! :--)
Cons: A bit pricey
