My somewhat inexperienced opinion too. I spent 4mo there while in college. It was fun. I think inflation was worse there since I was there in 2011.

I remember hearing about the inflation since the Korean War when a 700won payout was issued to the family of a fallen soldier, which was at the time worth about $0.50, maybe less.

Food then was cheaper. A 15k-won/person meal at a sungyupsal/bulgogi place was pretty good, which felt at the time like $13 does today.

I sorta learned Korean, but I didn't put enough effort into it to really converse. I do like their writing system, though!
