The Latin phrase meaning "to each his own," brought to mind by a discussion elsewhere of the relative merit of the art of Thomas Kinkade, serves as the motto behind the bar of a venerable Boston institution, Jacob Wirth Restaurant in the Theater District.
The historian Samuel Eliot Morison used to lunch there as a boy after Mass at the Anglo-Catholic Church of the Advent on Beacon Hill. The Hall of Fame plaques on the wall honoring great Red Sox players stop somewhere around Jimmie Foxx and Lefty Grove. German sausage and house dark highlight the menu at Jake Wirth's, which still appears much as it did in the 19th century.
Definitely Ad O's idea of a restaurant.
John Maihos offers a review of the restaurant and its history at About.com. Here's a Tufts site offering a tribute to Jake Wirth's in German. And here's the recipe for their sauerbraten.
