The space will include an auditorium, conference rooms, a large lounge area, small café market and a restaurant called The Chocolate Pig. Work on the restaurant involves utility work up through the five-story shaft for roof-mounted equipment, as well as added landscaping for an outdoor patio area to include seating, site lighting and a fire pit.
