On Saturday I found myself in the Mosel region and I followed a restaurant recommendation by my friend Yulia: Koeppchen in Wormeldange. My friend A and I got there at 6 pm to have dinner. The main dining area was fully booked but they found us a table near the bar area.
There were quite a few yummy things to choose from the menu, including some Luxembourgish dishes. I gave the vegetarian burger a try. The patty was made of mashed peas topped with goat cheese, tomatoes, green salad and hummous sauce. It came with a green side salad and I had asked for the fries to be replaced with boiled vegetables. The burger was good, perhaps a little bit dry, but it wasn't greasy and didn't give me the bloated feeling that one sometimes gets after such an indulgence.
I think that I would go back to Koeppchen in the future because I liked the setting and the service was friendly as well.
