Are there any Hooters restaurants in Korea?
Yes. However, there is just one in the entire country of South Korea (at the time of this writing). It's in Gangnam near Sinnonhyeon Station (sheen-nohn-hyuhn yuhg), Line 9. (Come out of Exit 4, look across the street, and you will see the Hooters restaurant.)
There was another Hooters restaurant in Yongsan, but it closed down.
