Wanna work at “Sons of Essex,” the soon-to-open successor to Mason Dixon? There’s an open call for all positions Saturday afternoon. The interviews will take place from 2-4 p.m. at the restaurant, 133 Essex Street. By the way, the wood shed has come down, revealing a new facade. Still to come: more painting and other finishing touches. Owner Matt Levine (previously of The Eldridge) has been pretty secretive about the chef, menu, etc. In appearances before Community Board 3 earlier this year, he said the restaurant would serve “New American” cuisine, paying homage to the neighborhood’s immigrant roots. Stay tuned!
