Hi-ho, hi-ho. It's off to work -- rather, to the Old City Civic Association -- goes Luca Sena, of Ristorante Panorama and the Penn's View Inn at Front and Market Streets. Sena wants to work with the owner of the Snow White, the longtime diner at Second and Market Streets across from the Continental. Plans submitted to the Zoning Hearing Board call for an outdoor deck and the addition of a second floor. Sena won't talk about it yet. Stay tuned.
