The owners of the Kalguksu (Korean noodle dish consisting of handmade, knife-cut wheat flour noodles served in a large bowl with broth) restaurant are parents of none other than IOI's leader Lim Na Young, who will also be debuting in Pledis Entertainment's upcoming new girl group, PRISTIN! 

They wrote in front of their entrance, "We are heading to Seoul to attend our daughter's concert. We will be closed for 2 days on the 6th and 7th. Apologies." Pristin, who were known as Pledis Girlz until recently, held their final concerts before debut, 'Pledis Girlz Hi & Bye', from January 6-7. 

Netizens shared a photo of Lim Na Young's parents' adorable sign, commenting, "They're so cute...", "But the kalguksu there is actually really good and they give you a lot", "Kekeke they must be proud of their daughter!", and more. 

Can't wait to see Lim Na Young debuting in PRISTIN!
