Finally i made it to one of the Loving Hut restaurants while my last Paris trip. The international chain of vegan restaurants, opened by followers of Supreme Master Ching Hai (soon I will read her book and post about it, its already in my bookshelf;) has even a whole vegan hotel in austria!!
its a nice place with great food and very friendly people!
you find it at the metro station Saint-Sébastien Froissard (Line 8)
