Recommended bowl: Stinky AF
Master Moriyama-san previously worked at a few different ramen shops and even had his own ramen shop, then ran a bar for about five years before finally opening Kairyū 1992. The extra stinky tonkotsu soup is made using pork heads and back fat only, in the 'yobimodoshi' style of adding the leftover soup to the pot of the next day's stock. The noodles here a just a tad thicker than standard Hakata style, so they don't serve the extra al dente styles of 'konaotoshi' or 'harigane.' A bit funky but charming, the shop is on the larger side with 33 seats.
