 The Ritz Club is a casino in the basement of the hotel , occupying the space which was formerly the Ritz Bar and Grill . In the original structure , this was where the Ritz ballroom was located . A May 1906 edition of Truth magazine described the basement with the Grill Room and Banqueting Hall as palatial , ivory @-@ white in decor , with " mirrors on all the walls reflecting an endless intersection of arched ceilings " . The rooms were used for dinners , balls and theatrical shows , with a stage at the south end of the Banqueting Hall . By the mid 1920s the Grill Room had been relocated into the Banqueting Hall , and furnished with circular tables with oval back wicker chairs . One 1926 brochure stated that it was the scene of " some of the finest private and public balls ever given in London " .
