General rule of thumb: don’t go to tourist spots or where something has been invented. It’s worse than the knockoffs.

Real “Sachertorte” from “Hotel Sacher” in Vienna is mindlessly overpriced and way worse than any one you can get at any small local bakery.

Original “Carpaccio” from “Harry‘s Bar” in Venice is the same - extremely overpriced and just not good and not worth the money.

I’ve had amazing “Tunbrötsrulle” at some little restaurant in Stockholm, I’ve forgotten the name, but they also had burgers on the menu.
