30 Rockefeller Plaza
People wanted to use the roof of the building for entertainment. The 67th, 69th, and 70th floors have places where people can look at the city from high above. The highest one is the "Top of the Rock" Observation deck. These places were opened in July 1933 and many people went there. A restaurant called the Rainbow Room is on the 65th floor. The Rainbow Room opened on October 3, 1934.
