Help buying from SEOUL, Korea (any Korean mech fans around here that can help?)

[derzemel]

I have a friend that is leaving on a trip through Korea and Japan on the 20'th and I have begged him to buy me a Leopold FC750R and a Leopold FC210T
I already gave him the map and address to Leaderskey and to Yongsan

The main issue is that he is going with an organized group and they will be staying only one day and a night in Seoul and they have a tight schedule.
They will be checking at a hotel next to the Dankook University campus: https://www.google.com/maps/place/Dankook+University/@37.3219777,127.126868,15z/data=!4m2!3m1!1s0x357b5755cbac9e51:0xda0d379a7fe9c5f3

They will be staying half a day at the University and the other half a the Romanian Embassy in Seoul. So not much time to get to Leaderskey.
Now, my question are there any places close to the Dankook University where my friend can buy a Leopold keyboard and numpad? Or are all the shops in Yongsan?

Also, can you direct me to some Korean forum where I can ask this question?

Thank you!
