I've had got my lunch here few times and whilst it's good food, it's a bit expensive for what it is. However the food selection is pretty good, with lots to choose from though nearly all of them are kind of spicy.
The man who runs it is really nice, and speaks English for those who find French a struggle. He also sells spirulina and various teas and things.
If you're wondering where to eat your food once you've got it, I recommend the parc de milan, which is about 10 minutes walk away.
Cons: Quite expensive, A bit too spicy
