Psy Won't Go After Gangnam Style Restaurant

The Koreatown restaurant was previously known as Soju Town -- but it re-opened last month after a brief closure under its new name "Gangnam Style," clearly an homage to the popular song.

The restaurant never bothered to get Psy's permission to use the name -- but sources close to the singer tell TMZ, he doesn't care ... because where he comes from, imitation is a form of honor.
