Recommended bowl: 70+ years in biz

As the name states, look for the red noren hanging outside this shop. Family owned and operated for over 70 years, now with the third generation (the original owners’ grandchildren) running the business. They have three shops total in Japan, including one in Roppongi, but this OG head branch is by far the best. The noodles here are slightly flatter than your typical Hakata style, but everything else is classic Hakata tonkotsu goodness.
