Partner Kevin Heisner (Lone Wolf, Pub Royale, Queen Mary Tavern), who owns the former Nightwood building in Pilsen (2119 S. Halsted St.), said exterior painting began Tuesday, bright white covering the previous dark brown. The open patio will be enclosed with greenhouse glass, and a heated floor installed to create an all-season space. White lace curtains have been ordered, and white marble counters will be installed, said Heisner. (Though Heisner is a partner in Heisler Hospitality, he says this project is not part of that group.)
