Neighborhood: Upper East Side
Address: 845 Lexington Ave.
Why you should go: Learn the secret of how Mad Men-era guys and dolls managed to survive those three-martini lunches—smaller glasses! Donohue's 3 oz. 'tinis are pretty good, too.
Open since 1950, Donohue's menu hasn't changed much since then; it's a living testimonial to how lame Manhattan's culinary scene was 60 years ago. Craving an individual can of sardines or London Broil? Donohue's has 'em both. The clientele is vintage, too. As the old joke goes, "the average age is deceased."
