Context: The Kimpton Sir Francis Drake Hotel is a 416-room boutique hotel located in San Francisco, California at the corner of Sutter and Powell Streets adjacent to the city’s central urban entertainment and shopping district, Union Square.  The property was named after the English explorer who, in 1579, narrowly missed discovering San Francisco Bay and instead sailed the Golden Hind into Drake’s Bay 28 miles north.  Built in 1928 by Midwestern hotel developers Leon W. Huckins and John A. Newcomb for the then princely sum of $5 million, the hotel was run by several major hotel companies before being purchased by an investment partnership led by Bill Kimpton, founder of Kimpton Hotels & Restaurants, in 1994.  Kimpton sold the property in 2005, but still manages the historic hotel.  In addition to its Union Square location, the Drake is known for its opulent, Renaissance-style interiors, Italian restaurant, Scala’s Bistro, and as the location of a 21st story nightclub that has been a city attraction for decades, The Starlight Room.
