The Theatre Development Fund will finally (after three years) open their newly designed shiny, glowy, red-steps-to-nowhere TKTS half-price Broadway ticket booth in Duffy Square on Thursday around noon. Bloomberg will cut the ribbon and probably answer some questions about term limits. In the meantime, it's all roped off. But the statue of song-and-dance man George M. Cohan is all spruced up and ready to eyeball. Looks mighty nice silhouetted up against the neon Coke sign.
