We went there only once and only had falafel sandwich. Therefore, beware, this is a very limited review!
However, we absolutely loved the crispy and tasty falafel and the simple but decent sandwich it was wrapped into: hummus, tomatoes, lettuce, onions & spicy sauce). Also, the staff was superfriendly and they're very happy if you speak a bit of Arabic ;-)
Note: 1/2 of us lived in the Middle East and we are both not easily convinced (and fooled) when it comes to Falafel...Pros: very friendly staff, super cheap, amazing falafel
Cons: rather meat-heavy place
