Personally, the ultimate company cafeteria was Suwon Samsung

I've tried them all: the Geoje shipyard cafeteria, known for great meals;
the Hyundai Motor Namyang R&D Center cafeteria;
and the Chosun Ilbo cafeteria in Taepyeong-ro.
Not only were Korean, Chinese, Western, and Japanese options standard,
but they even used premium-grade kimchi suppliers.
Of course, I don't have any photos since it's been several years since I left.
I was such a fool to leave that great job ㅜㅜ
