Japanese bar

Personally speaking, I love japanese food. Even I like japanese drinking culture also. Although I'm not a drinker, and I have not deep knoweldge in alcohol, I love atmosphere getting along with peoples very freindly through alcohol.
My brother guided me to japanese bar, which once was so popular, so I could see many signature of famous entertainers including Yon Sama(Bae Yong Jun).
It seems to me that interior was so similar to Japan, and served menu was also very similar, however it was so expensive.
I ordered o-deng, my favourite food with Asahi draft beer. Talking and talking, drinking and drinking.
Today I was so happy to enjoy japanese food that I can't take so often, because it's not easy to find good level's restaurant and bar.
