With the end of the 19th century, in 1893, the Convention Plaza Hotel and Conference Center, built by the famous hotel developer R.H. Southgate, was opened as an annex to the auditorium. Centered on its unique appearance, this well-designed hotel quickly became a favorite among Chicago's industrial, social, political, and cultural leaders. Today, after nearly 125 years of improvement and refurbishment, Congress Plaza Hotel has become one of Chicago's most historic hotels, and its story is as colorful and fascinating as Windy City. The original bathroom plumbing at Congress Plaza Hotel was replaced in a 1923-24 renovation. In the early 1930s, the pre-Elizabethan-era room on the first floor was transformed into a stylish nightclub with a revolving music stand. Renamed Joseph Urban Room, it became the headquarters of the legendary Benny Goodman on the NBC radio in 1935-36.
