Incheon Airport's Hall of Korean Wave

Before the school year began, I had a 6 hour layover in Seoul's Incheon Airport. While there, I noticed signs pointing towards a "Hall of Korean Wave". Unfortunately, I touched down at 3am with a connecting flight departing at 10am, so I didn't get a chance to go into the Hall of Korean Wave. However, it did spark a question in my mind - "What is this Korean Wave, and what's so great about it that it deserves its own museum in the Incheon Airport?" Now, having signed up for this course, I've taken the opportunity to revisit this question, and did a Google search for this Hall of Korean Wave, and found this page, which describes the Hall of Korean Wave:
"Visitors are invited to watch free screenings of ‘Winter Sonata’, ‘Autumn in My Heart’, and ‘ Daejanggeum’ on a large screen. There is also a Star Photo Zone where life-size photos of Korean Wave stars are set up for picture-taking. The shop offers a great opportunity for those visitors who haven’t had time to purchase Korean Wave-related souvenirs. And they can spend the little time left before departure enjoying Korean pop culture.
Address : Duty Free Shop, Incheon International Airport, Unseo- dong, Jung-gu, Incheon-si
How to get there : Incheon International Airport, Departure Level Duty Free Shop opposite Gate 46
Telephone : +82-32-743-2143(Korean, English, Chinese)
Business hours : 7 am – 9:30 pm (All year round)"

And apparently, Incheon's Hall of Korean Wave isn't the only one of its kind. The page also talks about shops in Seoul taking advantage of the Hallyu craze by selling movie and TV drama memorabilia. Has anyone in the class been to any of these shops?
