I went here twice, both times I chose a sandwich with marinated tofu, olives and pepper (which, by the way, was DELICIOUS) and it was served with salad.
One of the 'salad-parts' had this weird dressing thing on it, that did not look vegan at all. I asked them, and they assured me that everything on the plate was - in fact - vegan, so therefore I took a tiny tiny bit, but no. It tasted like mayo (or something similar, if that even exsists, I don't know).
Despite all of this badness, though, I must say that the cafe itself was lovely, and that the sandwich was the best sandwich I've ever had.
Cons: The (non-)"vegan" mayo
