Well, not PDX proper, but Beaverton. At lunch today at Hakatamon I spotted a notice (it was inserted into every menu) that starting April 1, they will be introducing hakata style tonkotsu ramen, in addition to champon and sara udon. The notice boasted of a 12-hour stewed broth.
I sure hope it’s not an April Fool’s joke.
Ooooh! Shiny! Must brave the wilds of Beaverton to see if this is true.
