Usually famous people get their “people” to book restaurant reservations etc often making a whole production of it, asking for things like private dinning rooms and then sometimes telling the media the time and the name of the restaurant.
Once in a while however, if they’ve been filming/working they might just want a quite supper and secluded corner of the restaurant.

At first when the owner told me she was in the building I resisted the urge of other staff to “sneak a peek”.
Michelle asked to speak with me after dinner, so I hurriedly put on a clean chef’s jacket as soon as I was able and went to her table. Even dressed in casual clothes she looked good. She introduced herself as Michelle as if I didn’t know who she was then invited me to join her for a beer. She generously said a few kind things about my food the chat turn to the movie she was currently working on “Batman Returns”.
