We went here in October 2013, so I'm pretty late with my reviews!! Plus I wasn't strictly vegan when I went (but vegetarian). I was here with my meat eating boyfriend, who found the non-veg options interesting and tasty.
I had the mezze platter which I think is mostly vegan-lots of olives, salad, hummus etc. For vegetarians, there is a lot more variety than for vegans.
The price is reasonable, but probably on the expensive side for Fes/Morocco. Huge outdoor roof terrace which makes it worth visiting too!
Cons: Expensive compared to other places, Not much for vegans
