The steak was specifically 한우, or Korean beef, which is considered top-tier, akin to wagyu. The combo of instant noodles is known fondly as 짜파구리 and is not a working-class meal but rather comfort food, often eaten by teenagers as a joke. The blasphemy of tossing premier 한우 into instant noodles shows how privileged the Parks are: most people would never dream of wasting 한우 like that.

This review is so well-written. Thank you for the pointers!
