A CU convenience store near Hongik University features a wall with a huge selection of ramyun that can be prepared and eaten on site.
After a customer makes a selection he can then cook it in the store, as this video explains.
A store employee was interviewed about the library while I was there.
The location is Jandari-ro 25, Mapo-gu in Seoul. Take subway line 2 or 6 to the Hapjeong Station, exit 3.
