West side of Broadway from Bleecker Street to Bond Street. (No. 647 is the second building from the left), date unknown.

The building at no. 647 was originally the Coleman House Hotel. In the late 1850s and early 1860s, the vault of the basement housed a Rathskeller-like beer and wine cellar restaurant called Pfaff’s; it was a favorite haunt of the bohemian literary set, including Henry Clapp, Jr (editor of the Saturday Press and "King of Bohemia") and Walt Whitman. It was known as a place where men could meet other men, and it was open to women at a time when the sexes did not meet in such public company.

The saloon closed in this location in 1864 though it would move to various other buildings though much of the rest of the 19th century. This building's later tenants included a hat shop and an envelope factory. Today the original building still stands with a shoe store in the first floor retail space and a newly opened cellar bar that takes inspiration from its 19th century predecessor.
