We ordered a Prague cake.
The cake is generally delicious, but if it was just called "chocolate cake" or whatever, everything would be great. Because there would be no disappointed expectations. But why, why did you call it Prague, when it has nothing in common with classical Prague?
In general, if you are a connoisseur of classical Prague, then don't be fooled - you won't get it. And if you just like cakes, then you can order them.
