Are there any Hooters restaurants in Korea?
Yes there is. There is, however, just one in the entire country. 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 in Yongsan, but it closed down.
