The dishes are all vegan, the staff is vegan and very friendly.
Seitan is excellent, as everything else we tasted so far.
Prices are very fair, given the quality.
You can eat inside or outside.
In 2014 they moved to a place much easier to reach, and they changed their formula from classic restaurant to bistrot, no service at tables.
You should definitely try it if you have the chance. :)
