Does the presence of celebrities in a restaurant make the food taste better? Do the famous eat where the grub is good? A recent visit to the Whately Diner (sometimes called the Fillin’ Station), at a truck stop just off I-91 in the Massachusetts town of the same name, raised these unexpected culinary questions as I forked a plate full with eggs, home fries and corned beef hash. Such thoughts would not normally occur to me while enjoying some of my favorite comfort food, but the menu listed several of the big names that had stopped in for a meal, including Michael Douglas, Ernest Borgnine, B.B. King, Christopher Reeve, Vanilla Ice, Jason Robard, and the Beastie Boys. A scene from the 1999 film “In Dreams,” with Annette Benning and Robert Downey, Jr., was filmed on the premises. Looking around as nonchalantly as possible, coffee mug in hand, I confirmed that none of these personages, alive or dead, were present.
