Grenoble

I once mailed them asking if their food can be kept in the fridge as they were closed on the day I wanted to eat it. (I'd pick it up in the evening and eat it for lunch the next day, seemed like a reasonable enough question considering the kind of food/service they offer.) I received a rude email stating that they refuse to reply to a question like that as their food is meant to be eaten fresh. Any other restaurant would make suggestions, or at least be friendly about it, but not them. Unfortunately this has turned me off their restaurant forever. A good experience starts with helpful and friendly owners, if a potential client isn't allowed to ask a simple question... well...

Small place, pretty popular with locals. Only has plate of the day, in two sizes: small (€10) and large (€11). Variety of foods on plate from tofu to grains, salad, potato, chickpeas and a slice of tasty quiche. I assume this changes daily. Also inexpensive soup of the day and a desert.
I think if you are vegan you may be better calling in advance.
Owner very friendly.
The food was fresh and tasty, nothing fancy but a healthy, nutritious and satisfying plate of food.
No menu, but I like that. You just get what you're given!
