Kimchi, paella, shepherd's pie, gazpacho, po'boys and gnocchi are okay.
I would try any of the others if someone I knew (and trusted) recommended them as being particularly good, even though some of them (haggis, lutefisk) sound a little nasty.
Pierogies, gnocchi, sauerkraut, kimchi, gyros- yum!
Lutefisk is popular where I’m from but only tried it once. Think heap of whitish/translucent fish jello without much taste that just slips down your throat. Ughh- must be an acquired taste.
Also, Gyro is very US. In Australia (and I think Greece) we say Souvlaki for the same thing.
The "s" and "sh" sounds are the same phoneme in Japanese, so they're actually interchangable
