Ah, those are just the shitty "restaurant burgers", presented in that stupid way to try and upsell a cheap beef patty between two buns as a "dining experience" rather than fast food from a van or grillhouse.
They are inferior pseudo-burgers, because their shape is more vertical than horizontal, which makes the contents liable to spill out, and renders them non-portable, and impossible to eat with your hands, which violates the entire point of a sandwich, as outlined by >>6713
I would like to protest however, that you would call the Earl of Sandwich a "European".
Not only are the Eurofags generally leery of anything English having to do with them, but we have always considered Europe to be something that goes on "over there", and away from us.
This probably began with the religious schisms, but it really has stuck.
Only the faggy "world citizen" types among us ever try to link Englishness with "Europeanism".
