Looking for good houtou and tonkotsu in Tokyo
These are two regional dishes that I've had fantastic versions of in Yamanashi and Kagoshima respectively. I've eaten them in Tokyo as well, but never found anything quite as good as in their native habitats. Houtou is an udon dish in a very rich kabocha-based broth, and tonkotsu is a braised pork dish a bit like kakuni (and no relation to tonkotsu ramen). Has anyone found any great Yamanashi- or Kagoshima-style restaurants in Tokyo that serve these?
