This is one of my favorite places in Bonn! They have many many (more than 20 different) juices with vegetables and fruits for each 3,80 Euro! They make them fresh in a blender.
If You're vegan You can also eat all their soups (they're all vegan!). You can get some salads and summer-roles which are very, very yummy! If You want to have milk rice You can also ask for coconut-milk rice. The staff is very friends, unfortunately not a big place so You don't always get a seat! But they offer take-out. The soups and salads are very quickly made so You don't have to wait long!
Cons: small place
