Huge vegetarian buffet, almost entirely vegan. Lots of really fresh really good quality vegetables for salad makings, a vegan soup, a flat vegan pizza, some crazy vegan bread, some vegan dumpling things, 2 vegan rice bases, amazing seitans, fantastic tofus, great dishes that are just veggies, and they rotate them day to day (6 or 7 hot options). They also offer fresh juices.
The only things that are not vegan are one yogurt-based salad dressing (the people working will point it out to you) and the cheesecakes. Don't worry, though. If they have the vegan dessert it's WELL WORTH IT. "Cookies Cake". What is it? I do not know. It is a cube of delicious cookies and vegan cream stuff. The person working explained to me how to make it and showed me ingredients that said 100% vegetable on them but for which I have no american counterpart. If they don't have a vegan dessert, don't worry. You'll be groaning and rubbing your belly with pleasure at how much you ate during the buffet. My omnivorous mom keeps suggesting we go back there. Also, only 7.5 Euro for an all-you-can-eat lunch buffet, just a bit more for dinner.
