One Pocket Ghost is from Chicago, but he's in NY this week. I'm shocked you didn't find a game at Chris's. I head there every time I get to Chicago and have always found One Pocket, in fact I would rate it one of the top One Pocket rooms in the country. Featuring top pro Marco Marquez and patriarch Freddy Bentivegna and a slew of other strong players, I found that even the 9-ball bangers would play some One Pocket
Maybe some of the action has spread to other rooms a little, but I can't believe it has deserted such a great One Pocket town completely!
How about Red Shoes -- have you tried there? That might be a little farther out of town depending on where you are in Chicago -- I've never been there, but have heard it is one of the top suburb rooms...
