This place offers two vegan lunches every day, price is around 10€. You get a
mix of food (I am guessing the same dishes are available at the buffet if you go there in person), a small salad and a small dessert. Mandala is an all-vegan Indian restaurant. They also have vegan pancakes. When I ordered delivery from them (about 6 months ago) the packaging was styrofoam and plastic.
