One of the South End's most anticipated new restaurants is now open for business. After months of temptation and rumors of soft-openings, Yakitori Zai started doing prix fixe dinners by reservation a few weeks back, but Thrillist reports that the restaurant is now "flinging the doors open." Yakitori Zai's website confirms that it is accepting walk-ins and says it's expanded the menu "to include many more exciting a la carte menu options." At last, the long wait for chicken cartilage with shio is finally over. For a look at the complete menu, see here.
