We were staying in this Riad so ate here on our first night. We'd have been happy to eat here again but wanted to have a wander and see more of Fes.
There was a man playing a sitar and he was very good.
We had a bottle of red wine - lovely - & 3 courses.
Everything we had was delicious and the portions were not too huge like some places we've eaten at in Morocco.
If you're looking for a Fez 'feel' then the restaurant will disappoint as they've made it very modern. If you go when it's warm enough though you can sit at the outside/courtyard bar for a drink which would be lovely and would satisfy the need for seeing traditional architecture.
The Riad is near one of the car park/entrances to the medina so get a taxi and ask for directions, or follow the signs that are quite clear from the car park.
