The food is fresh, local and sustainably sourced. The cafe is also fossil fuel free. Both of these points are worth supporting.
The bread, cakes, sandwhich sand salads are very tasty. Specials are also delicious. There is free wifi if you are a student wanting to study off campus.
I really like this cafe and often stop here while in Athens. I also very much like the small shop. You just need to make sure you are not in a rush. Even when there are only 3-4 tables of three or less people that have ordered food it still takes 40 mins or more for food to be made.
