About

Harvard Square restaurateurs Deborah Hughes and Mary-Catherine Deibel continue their twenty-year fine dining tradition with UpStairs on the Square. Featuring two dining rooms, the multi-floored restaurant offers a choice between the large, wood-paneled Monday Club Bar, where guests can enjoy sweeping views of the Square, or the more formal Soiree Room, which is reminiscent of a glowing, colorful jewel-box-like supper club.

Striving for the same high standards Deibel and Hughes upheld in years past, this spot celebrates the bounty of New England ingredients and the handcrafted techniques that have always made their menus popular.
