I had dinner at Landia yesterday with a non-vegetarian friend. I had a vegan dinner consisting in seitan schnitzel (three pieces of seitan, potatoes, lemon, and a nice sauce), a natural juice (carrot, orange, ginger), and a piece of a vegan chocolate and coconut cake (there were 5 different cakes to choose from, and all were vegan!).
Everything was really nice, portions were generous, and staff was friendly (speaking to me in English and to my Austrian friend in German, of course). There were not many other customers, probably because it was Monday (in their website they suggest booking in advance, in fact). In terms of money, I spent 15.50EUR, which I think it's honest.
My friend had a vegan pumpkin-based dish (which he liked), a beer, a cocktail (mango dream), and a coffee and spent 20EUR.
We went away full and happy! :--)
