GANGNEUNG, South Korea — When David Chang tells you to eat something, I figured, you should probably go eat it.

I’d been talking to Chang, the famed chef and a fellow Korean-American, about the Olympics in South Korea, where he spent 10 days this month working as a sort of culinary correspondent for NBC. Our conversation turned to the local cuisine around Gangwon Province, which includes the Olympic cities of Gangneung and Pyeongchang, and the extent to which people visiting the Winter Games here seemed to be engaging with it.
