The Ritz Ballroom, Swimming Pool & Garden, North Point [1941-????]
"The Ritz Ballroom opened on 5 September 1947 on an empty lot next to the docks in North Point. [...] Next to the Ritz Ballroom was the Ritz Garden, with Chinese gardens, restaurants, two swimming pools and miniature golf." from http://hkpop.blogspot.hk/2008/09/ritz-ballroom.html
I only found one result for "ritz garden" in the newspapers, reporting that manager Li Choi-fat was in court (The China Mail, 1948-12-16, pg 3).
