One of the best BBQ meals I have had in Seoul. Besides the BBQ beef (really good quality), my personal favourite is the beef tartare, Pretty awesome food we had that night but yeah, prices are not cheap. The staff are really friendly too and they helped us called for a cab to get back to our hotel.
p.s. I didn't really fancy the steamed beef soup, the smell and taste is a little strong for me. However, subjected to taste and preference, our table had a 2-2 split vote on this (beef soup).
