Some observations:

Old and new

I expected all of Luxembourg to feel very old but most of what I saw is quite modern and even Ville Haute (Old Town) had loads of construction cranes, scaffolding, vehicles, and workers.

Language

Residents speak French, German, and Luxembourgish, which combines the two. The default, when someone doesn’t know which language you speak, is French. The vast majority of people I interacted with spoke fluent English, with only a couple shop owners saying they know just a little. As I approached strangers with questions, I would start with, “S’il vous plait.. English?” The funny thing was I began pronouncing “English” with a French, or generically European, accent 😂

Food

It wasn’t until I was about to have my first meal in Luxembourg that I looked up their typical cuisine. It sounded quite heavy, with meats and creamy sauces. That’s OK, I didn’t come to this region for the food 🙂

Expense

For one of the most expensive countries in the world, I somehow got off very easy. I was there 3 nights, 2 full days, and spent only $111.34 USD on food, drink, and ground transportation.
