The retail space in the building's "cowcatcher" at the "prow" was leased by United Cigar Stores, and the building's vast cellar, which extended into the vaults that went more than 20 feet under the surrounding streets, was occupied by the Flatiron Restaurant, which could seat 1,500 patrons and was open from breakfast through late supper for those taking in a performance at one of the many theatres which lined Broadway between 14th and 23rd Streets.
