I must confess to having gone on a wee bit of an Irvine Welsh kick, back in my younger years. I stopped at Filth I think, which I don’t think I finished, but I did enjoy his other books at the time, (I even watched the movie version of The Acid House). The man hisself will be signing copies of his new book, “The Bedroom Secrets of the Master Chefs,” at 6 p.m. on Aug. 14 at the Fashion Institute of Technology, Great Hall, W. 27th St. (at 7th Ave.). Because this thing is being at F.I.T., not just a regular old B&N, I get the feeling he doesn’t make it to this side of the pond very often.
