In 1928, the Delmonico Hotel was completed on the northwest corner of the intersection of 59th Street and Park Avenue. The design consisted of a tower emerging from the typical Park Avenue palazzo block which formed its base.

The Delmonico Lounge occupies part of the ground floor on the 59th Street side. The lounge can be accessed from the hotel lobby or from the street and is a double height space that can accommodate 40-50 people.  It is a room used mainly at night and is designed to create an atmospheric effect for drinking and socializing.

The teardrop-shaped bar is made of blue granite with a front face of lacquered gray-blue panels with inlaid horizontal braided copper ropes finished with a silver patina binding it together like an evening dress.  The walls are of dark blue lacquered panels with inset flattened copper tubes coiled up and arranged in a pattern of rising bubbles.  The upper wall areas are made of sound-absorbing blue fabric surmounted by a continuous band of blue mirror.

At the corners of the room are four large three-tiered light fixtures built into the walls consisting of copper armatures set with curved surfaces of hammered copper coils that create a shimmering, glowing light within the space.  The ceiling is dotted with small white and blue low voltage lights to resemble stars.

The intent of the room is to evoke a tradition of New York night clubs and watering places which speak of indulgence and excess and are a deliberate night time contrast to a city which prides itself on rigorous commercial endeavor by day. This dichotomy of the city is expressed in the opposition between the rigidly formal symmetry of the existing hotel lobby facing Park Avenue and the sinuous interior organs of approach to the lounge whose sensuous and curvaceous forms are visible from 59th Street.
