trying to find a Cuckoo Clock Store i visited years ago in Europe it was near the Black Forest and perhaps in the area of Lake Teetazaine?

It was in Germany. Europe is not a country.

Titisee, Schwarzwald, here you go:

Yes, I'm well aware of the teenage jokes people make about Titisee, but imagine you live in a village called Anus. Well, that's in France.

(linguistics add-on)

"der See" is the lake in German, "die See" is the ocean.

I won't research, however, why the Titi lake is called the titi lake. I leave that to your fantasies.

the entire area is known for cuckoo clocks. there are probably several in the same neughborhood.
