When I first visited Japan, Fukuoka, I saw a bridge with a long queue. At the end of the line, there was a street stall selling Ramen. I walked back, stood on the line, and tasted it.
There was a whole new world there!
Unfortunately I wasn't able to try it again, before I stepped into Menyasandaime in Hongdae, Seoul. I really recommend this place if you want to know how real Ramen tastes:)
