91 George Street is aesthetically significant as a well-detailed Victorian Italianate hotel building of the late 19th century. It occupies a prominent corner position in two 19th century commercial streetscapes (George Street and Argyle Place) of State significance that demonstrates the scale, pattern and appearance of 19th century commercial development in Sydney.
The former hotel was rebuilt in conjunction with No 93 George Street in the 1890s, and shares many decorative details with its smaller and less prominent neighbour.
