What exactly is Seomyeon Rotary? (Leaving on High 1 Tour bus)

Hello everyone

This Saturday morning at 3am we'll be leaving from Seomyeon Rotary on a tour bus to High 1. I am having trouble locating the exact direction of Seomyeon Rotary i.e. where to go to get picked up. [Update: in front of Woori Bank] Anyone have any tips? Anyone taken this bus before? (High 1 Bus)

My question that remains, though (since I can't delete this post), is: is Seomyeon Rotary just the general area around the subway station? Or is it an actual location?

Thank you thank you!
