First off, I saw shrimp salad in the self-service fridge right after coming in, so I was a little displeased after expecting a purely vegetarian restaurant.
But all the warm dishes I saw (and tried) were actually vegetarian: "plat du jour" fried rice, sweet potatoes, and veggies for 8€, "soupe du jour" (pumpkin and other veggies) 4€, both very delicious, and a "tarte" (gluten-free from chestnut flour, with green peas) 5€. I think that none of it was vegan.
Simple self-service restaurant with seating or take-away. Delicious food!
