In which venue did the Beatles play the most shows?

According to the club's resident DJ, Bob Wooler, the Beatles made 292 appearances at the club between 1961 and 1963, culminating in a final appearance at the venue on 3 August 1963—one month after the group recorded "She Loves You", and six months before their first trip to the United States.

The Beatles’ Star-Club shows were the culmination of endless hours of practice in the Hamburg scene. Between August 1960 and December 1962, the Beatles played over 250 nights in the seedy seaport city, and venues often demanded they play four or five hours a night.
