The most expensive hamburger I've ever eaten....was a $29 burger from a 2012 visit to NY City. It was a late lunch on some oddball street in Manhattan. Was it even worth $29 (didn't include the drink or chips)? I doubt it. But once you figure the rent for the establishment, the ingredients, the bun, and the local wage situation....with taxes figured up....that made a decent burger overly expensive.
In Copenhagen, on a one-day 'waltz' though the city, I had a decent 12-Euro ($15) burger that had neutral-tasting mustard, stale pickles, and non-tasting graded onions.
Four years ago in the Wiesbaden region, I had a terrific hand-packed burger (about as thick as you can make a burger), for around 17-Euro (included the drink and fries).
Back in 1980, I had this bar-b-q 'shack' in Tacoma, Washington that served a burger with some mystery sauce applied....that would make your heart melt on the unique taste. They soaked the burgers in this sauce....to give you that smoky 'feeling'.
In Panama, at the NCO Club 'shack', they served a burger that was dripping in grease (probably a whole shot-glass came off the burger while on your table).
Last year, I ate a German-made burger which had tiny bits of spice-up cheese fused into the meat as it grilled. Frankly, it's the wrong way of making a burger, if you ask me.
The Krystal burgers of 1975? 25 cents with a paper-thin piece of meat and what seemed like a half-onion chopped up, with spoon of mustard? I would eat around six of these....to make myself feel full.
The worst burger experience ever? I stopped at some place in Munich, Germany around 1984, and had a burger which was 50-percent beef and the rest 'filler' (don't ask). About halfway through the burger....I pushed it to the side.
