>>212928278 (OP)been twice for work:
Ulsan was pretty standard industrial stuff, but went to gyeongju on my day off and it was pretty cool
Seoul is impressive in many ways, loads of neat stuff, but I massively preferred my time in suwon and seongnam
I've also spent some time in Yeosu, was pretty interesting exploring the expo stuff when no one else was there, also the whole yu sun shin stuff is neat
But also food is amazing, as long as someone local is with you, it's hard to know where to go without korean, but that is a good thing in my opinion
Main things that annoyed me:
work culture is horrific
rains all the time, but it isnt designed for rain (for example, I couldnt cut through suwon train station from the west side to the east, so ad to walk outside around it)
weird political stuff in seoul, and weird ads on the train about korea owning some rocks instead of japan
