This is La Grande Mosquee de Paris.
I friggin’ love it! The mint tea is hot and sweet and wonderful. The pistachio cakes with coconut are divine. And the ambiance is bright and colorful and so not Parisian (and yet, it is Parisian, because there you are and there it is!).
It has a fantastic gift shop and on alternating days, men and women can visit the hammam for baths, scrubs and massages. Oh, you can also see the guys worship there.
