Don't you think a North Korean restaurant in Gangnam would be a huge success?

‌
Among North Korean defectors,
if you gathered those who used to work in North Korean restaurants,
had them wear
North Korean style clothing and serve customers..
and if they used a Pyongyang accent..
I feel like it would be packed with tourists if they sold Pyongyang Naengmyeon.
Looking at YouTube, many Koreans visit
North Korean restaurants in Sinuiju to eat.
The view counts are very high, and people seem very interested.
