A wise ramen adventurer once said: "all these tsukemen shops taste the same to me." Quite frankly, I'd have to agree. Even at Gensuke, a so-called Hakata-style shop, I felt like I was back in Tokyo at one of the popular tsukemen joints. Don't get me wrong, the Tokusei Tsukemen here at Gensuke is bomb, but I wasn't sure what "Hakata-style" really added to it or took away from it. Nevertheless, I was happy and satisfied with their Tonkotsu/Gyoukai soup and thick, chewy noodles.
From Hakata Station head West on the main street. Stay to your right as the street splits and make a left at the 7-Eleven (the 2nd one). Then make a quick right and you should see an entrance to Canal City next to the Washington Hotel. Head to the Raumen Stadium on the 5th floor. Open everyday from 11am to 11pm.
