Menger Hotel added new saloon area to the hotel. This bar would come to be a huge success among both the local citizens as well as famous celebrities. The Menger Bar, as it is known, gave off an elegant appeal with its "ornate mahogany tables and chairs... large mirrors... fine crystal and sterling silver." The bar of the hotel is connected to Teddy Roosevelt, because it is where he recruited and met with his Rough Riders organization. Additionally, Hermann added a fourth floor to the Blum Street side of the hotel. The ever-growing demand for rooms became the hotel's most pressuring need.
