Hapa Ramen doubles its cumulative presence at Ferry Plaza next week. Starting Sept. 7, Richie Nakano's traveling noodle shop will sell at the Ferry Plaza Tuesday market, in addition to Nakano's regular Thursday slot. Knife sharpener the Critical Edge has dropped out of the Tuesday Market (it's keeping its Saturday slot, however), leaving an open stall.

But Tuesday's hardly the extent of Hapa's expansion. Monday, Sept. 13 is also slated as its pop-up debut at Bar Tartine, from 6 to 10 p.m. Hapa plans to hold court at Tartine for the remaining Mondays in September, too.
