Keanu's Duck & Dash

TMZ spotted brooding Keanu Reeves coming out of L.A. eatery Orso -- though he didn't make getting a good shot easy -- the shaggy star kept his head down, trying hard to hide his face from waiting photogs.

Keanu wasn't the only one who left people wanting more; we also spotted Sharon Stone turning down a autograph seeker's request to sign a photo as she dashed out of Mr. Chow with what can only be described as a dead ostrich around her neck.

R&B artist Keisha Cole was the only one of the restaurant-bound celebs who was happy to be caught on tape and autogrphaph photos -- Sharon, Keanu and Tyrese, take some notes!
