I was there 3 times, and the first two was just nothing impressive, if not a bit boring food. But the last time I went there because I was craving for a GOOD cake. Arriving there they only had one "peanut tarte", which was a dry sweet cake with salty peanuts on top. My friend ordered crepes, and they served the crepes that were standing there for hours with cheap vegan cream.
I haven't tried the new vegan places yet, but I'm glad this is not the only vegan place in Cologne anymore. I don't like it at all.
