Seoul pro tip: Google Maps doesn't work there, local apps are trash, and Xiaohongshu recs are all tourist traps.

Here's the real alpha from someone who actually eats (yeah I know how I hit 180lbs):

오발탄 역삼점 - Grilled beef intestines that'll change your life
용광쭈꾸미 을지로본점 - Grilled octopus, Euljiro OG spot
3대삼계장인 - Ginseng chicken soup, the real deal
Odarijip Ganjang Gejang - Soy marinated crab, no debate
진옥화할매원조닭한마리 - Chen Yuhua's whole chicken, iconic

Korean BBQ and Hanwoo bingsu? Walk into ANY spot. You can't lose.

If you're in Seoul and not eating like this, you're ngmi.
