OK, a story I have to tell. When we visited Trier, I noticed that the big department store in the center of town had MARX over the door. I looked things up and realized that 1) Karl Marx was from Trier and 2) his wealthy family had a store there. So he had some first hand experience with capitalism.
It was a really nice store but I don't think they had any foods, it was mostly clothing etc.
Trier was a fascinating place to visit, they were celebrating a birthday for Emperor Constantine, who was born there, and for whom Constantinople was named. All three of the main museums in town had extensive exhibits about Constantine.
FWIW Trevirensis = Trier was an important Roman town as was Köln, Cologne. MANY Roman ruins.
