Where Am I?

OK. I'm in Southern California visiting relatives and friends. Tonight we went to dinner at a local hangout. During dinner two celebs walked in. I wouldn't have recognized either but my daughter, who has radar for such things, spotted both immediately. The first was Fran Drescher, who is reputed to star in some program called "The Nanny". I didn't recognize her. But the second star radiated appeal. She was Scarlett Johansen, who showed up in sweats, a ponytail, and glasses. I was quite surprised at how tiny she was. There seemed to be some business transaction taking place - something about a script. We tried to overhear as much as we could, but it would have been too tacky to have listened too closely. My daughter did *not* try for a photo or an autograph, as we explained that stars are entitled to their privacy too. Nevertheless, they do hang out, just like regular folk. All I can say is that we were dressed more nicely than any of the Hollywood types in the restaurant. So, any guesses as to the restaurant where we ate? It is famous, although you have to keep up to have noted this one.
