Excerpt:
I ask her to tell me about her famous boyfriends, like Quentin Tarantino. "He has a pretty big one," she says.
"Did he know how to use it?"
"Yeah. He was great. Very tender."
"What about Chris Isaak?"
"Huge one. Too big. Unpleasantly big. But really masterful. He knows a lot about women and about sex." The restaurant seems very hot all of a sudden. "He was very romantic and played songs in bed. He had a ukulele on the wall, and he would pull it off and play it."
"Naked?"
"Oh, yeah. He was adorable. But I could never relax because I had loved his music for such a long time."
