There is more though, the best thing about the whole article is the wonderful table that accompanies it:
"Number of Korean restaurants located abroad (The number excludes Korean restaurants owned by overseas Koreans)"
What? If overseas Koreans don't own these restaurants then who does? Domestic Koreans? Non-Koreans? Who owns these 6,990 restaurants? The Korea Food Service Information board has done a cracking job in making this table clear and useful for all who chance to read it!
So how many Korean restaurants owned by overseas Koreans are there? Will we ever know?
On a brighter note, Andrew Salmon wrote a much better article titled "Globalize Korean Cuisine not Korean Food Exports" for the Chosun Ilbo a couple of weeks ago.
