We love couscous. In the US, it was hard to find a good couscous restaurant. In Nantes, there are quite a few. this one is in the St Felix area.
This one we particularly loved. The service is friendly, the prices are reasonable and the room is nicely decorated, full of vibrant colors.
We tried a bit of everything. It was all good, meat was tender, vegetables full of flavors. The desserts were good too.
You may want to reserve first as it is not super big.
