should go gangnam dong neh.
apujeong apparently is the rich & flashy - means u are
paying for the marketing etc.
actually if you think about it, apgujeong-dong is in gangnam-gu.
LOL ok gangnam-dong is a different thing, but you get the
meaning 
there is this street near teheran-ro which is famous for being
where all the cosmetic surgery clinics are located. pity moi jjib
is on the other side of that area... near the sm building~
remember used to commute from apgujeong-dong to hong-dae and
i-dae areas. felt like a totally different country. 
things were like half price there
