I went to Athens with a group of friends in the summer. There are a lot of vegetarian options on the menu, but only a couple that are vegan or can be made vegan. I got the falafel plate and was not disappointed. The falafel was great and it came with a greek salad, rice and hummus.
The restaurant itself is cozy and the service was great. It didn't take long for the 8 of us to get our meals.
Cons: few vegan options
