Patrick Dempsey left Nobu's Malibu outpost Saturday after a low-key dinner with friends. It was his second late night out in less than a week after Patrick and his Grey's Anatomy costar Ellen Pompeo hit Dan Tana's. The eighth season of their primetime drama is about to start shooting, though we'll have to wait until the Sept. 22 season premiere to see what lies ahead for McDreamy and Meredith. One thing's for sure; Patrick's having a successful Summer at the box office. His worldwide hit Transformers: Dark of the Moon has earned more than $750 million internationally, and next month he stars opposite Ashley Judd in the crime caper Flypaper.
