Club 546 was the name used for this long-time bar in its final years in existence. Located in the Royal Hotel at the corner of 5th and Michigan, the bar had long been a gay and lesbian bar, cafe, and meeting place, and continued to hold a strong clientele to its final days.

This bar was known simply as the Royal Hotel Bar when it first began to be frequented by gay people. By about the mid-1930's it was already recognized as a popular meeting place for gay people in the Milwaukee area. By the late 1960's it was operating under various names, including "The Stud" and "Club 546".

In 1971, when the GPU News began publishing its monthly GPU News, the bar was first advertised as The Stud Club with a "large dance floor". But by late 1972 is was advertised as Michelle's Club 546, sometimes mentioning both a Gallery I and Gallery II, with the former being a 24 hour Cafe with more casual sandwiches etc., and the latter being a more formal Dining Room.

The end came with news that the Royal Hotel was to be torn down to make way for a new Red Cross Insurance building. According to an article in the September 1973 issue of the GPU News, Michelle's bar would be closing its door for the last time on Sunday, September 23, 1973, after some 40 years of being a haven for gay people to meet and socialize- surely the end of an era.
