It's a nice "international" restaurant where you can find some vegan options for lunch/dinner. I had rice with grilled vegetables (aubergine, courgette and banana) and it was really tasty although way too pricey! As well as the juices! Staff is very friendly and there is wifi available (good for tourists). They also have a nice terrace in the street. Not so many options but we'll, there are a few and, as others have written here, sometimes you get tired of rice with beans!
Cons: Pricey, Very "international", Not that much options
