Eater suggests that it's true, and that the space will be called Chi Spacca, which translates to "cleaver" in Italian. We might not have Eataly yet (coming soon?), but at least we'll have more Mozza.
The exhibition kitchen and communal-tabled dining room adjacent to Mozza 2 Go opened in 2009, a beautiful intimate room that felt like it could be in Silverton's, or partners Mario Batali and Joe Bastianch's, Italian villa. First the space was used for classes and themed family-style weekend dinners, including the fantastic Saturday night pig dinners, and in May the Scuola opened every Thursday night for a casual drop-in salumi bar featuring some of the best house-cured charcuterie in town among other things (here's a recent menu). This apparently was a success, as we suspect this new Mozza sibling will have similar offerings, just every night and not once a week.
The rumor that the space will open as Chi Spacca in February doesn't seem like a stretch, especially if there won't be too many cosmetic changes. January is still filled with weekend pizza-making classes and dinners (Friday nights feature a citrus-focused menu this month), so there probably won't be. We'll have more details as they come in.
