One complaint I've heard about visiting Germany, for example, is there's nothing but German food.

That's nonsense. You actively have to inconvenience yourself to get German food, and it's basically only eaten by boomers and tourists. On the other hand, you can get genericized Italian, Turkish or Vietnamese food basically anywhere that's not a tiny village.

Admittedly, the quality is usually not the best.

I'm currently in Italy on vacation and it's hard to have a bad meal here - usually in tourist hotspots, or like take-away.
