With a name such as "Le Vegetarien", I would expect it to have a wide variety of veggie cuisine, including soy burgers, or tofu, or seitan. However, they only offer conventional (but meatless) European fast food (quiches, salads, pasta). Still, it is a nice canteen to have lunch if you happen to be nearby (I don't think I would make a trip especially to eat here), if you don't mind eating from plastic bowls with a plastic fork. Prices are good (3.90€ for a quiche or a small salad, and menu options for under 10€).Pros: Affordable (< 10€ menu), Natural fruit juice, Fast service (food is ready to eat&go)
Cons: No special veggie food (soy, seitan...), Open only at lunchtime, Plastic bowls, forks and knives.
