I actually find the topic of ads within a drama fascinating, and if it weren't for my blogging activities I would not have noticed 'em at all (except maybe if it's blatantly obvious like Style's, bleh). Whether you like it or not, it's business and dramas need to be profitable (you'll faint if you find out how much SG's advertising revenue amounted to).
DH don't need no product placements, 'cause it's pratically a walking advertisement for the JYP family. The people, the songs, or more specificly the kpop industry in general. Unlike the norm, in this show the producers do not take a backseat, they're pretty hands on and flamboyant (especially the latter, if you think of JYP's red silk outfit). This time, it's Bae Yong Joon's restaurant venture in Japan that has attracted the audience's attention.
Featured in February 7th's broadcast, when Kim Soo Hyun was in Nagoya, Japan for the school's field trip. He waited and waited for Hye Mi, and goes to a restaurant to find a Japanese friend. Well that place is run by Yonsama, a Korean restaurant with a traditional decor. It's at that place where Sam Dong witnesses the childhood sweethearts kissing in the cable car, and collapses from shock (it's Baek Hee's darn pot, I tell you).
Bae Yong Joon's agency, KEYEAST revealed: "That restaurant is KEYEAST's Japan branch, DA. The Korean traditional restaurant has been operating since 2006 and it's first outlet was in Tokyo, and that particular restaurant is currently preparing to move. Since then it has been expanding its business, and in year 2008 and 2010 branches has been set up in Nagoya's Lotte Hotel and Tokyo's Kinshicho.
