If you happen to be vegan and ask yourself where to eat, here are a list of vegan friendly restaurants in Marseilles :

There is also a very good falafel restaurant near the old port :

It is also easier and easier to find vegan food in supermarket in France, but if you're coming from Berlin, New-York or Tel-Aviv, you'll think we're still dwelling in the dark ages ;). Note that it's not possible to cook at Biblibre, there is just one or two microwave.

As a french vegan attending the hackfest, I'll be happy to help any other vegan looking for good food !

Yours,
