Are you feeling バカ (stupid)? Then you've come to the right place. No, they're not trying to offend you but the several idiotic (baka) items on the menu might. I've never tried them but I've heard the toppings can get pretty crazy. If you're feeling relatively normal then it may just be better to go with the popular items like Hanjyuku Tamago Ramen, Iwanori Tamago Ramen, Chashu Ramen, or Fukuya Mentaiko Ramen. Or even just go with the simple Ramen like I did. It'll give you a good taste of tonkotsu without having to travel to Hakata. There's no ticket machine here so just grab a seat and yell out your order.
From Shindaita Station you'll travel in the same direction as Bassanova (exit the station, cross the street, and go right) then continue for about 5 more minutes north on Kannana-dori until your body permeates a wall of stinky tonkotsu. Trust me, you'll know what I'm talking about. It opens at 6pm and closes at 3:30am or 4am depending on the day. You may not want to take a date here unless of course she's as crazy as you about ramen. (That reminds me, remember that girl that kept checking out Brian right in front of her boyfriend? Dude you should've made a move. I woulda had yo back...haha.)
