Restaurateurs Mary-Catherine Deibel and Deborah Hughes have found a new home and a new name for the much-missed UpStairs at the Pudding. UpStairs on the Square occupies another former Harvard social club and theatrical club, built in 1906 on Winthrop Square, in the heart of Harvard Square. The main dining room is an heir to the celebratory dining room at the Pudding and serves chef Amanda Lydon's beautiful fine dining menu with seasonal ingredients beautifully prepared and served. Enjoy this unique atmosphere with a $100 gift certificate.
