The Maisel, home of the famous Egg Mountain. A chain? Don't know. Don't think so. Arthur Maisel owned a restaurant called the Virginian, I learned by googling - which led me to a 1952 New Yorker piece (by William Shawn! He left the office? Really?) that namd other restaurants: the Texan, the Californian and the Georgian. These matches may have been used for all of his ventures.

Meet you at the summit.
