This afternoon at 1 p.m.  I am set to have a phone interview with Liza Minnelli. As always, readers of the Buffet, please feel free to leave your questions for her in the comment section and I will do my best to ask them. The interview was set up to promote her Oct. 12-14 appearance at the Luxor. This morning, however, it was announced that she will also be doing a second stand at the pyramid-shaped casino Nov. 23-25. Though people think she probably appears here all of the time, this will be Minnelli's first Las Vegas performance in eight years.
