The media anticipated that "Jack Rockefeller's saloon and dance hall" would become a major draw for the elite and the famous. In the decade following its opening, the Rainbow Room hosted former Spanish queen Victoria Eugenie of Battenberg; Norwegian Crown Prince Olav and Crown Princess Martha; and Swedish Crown Prince Gustaf Adolf and Crown Princess Louise. The Rainbow Room became frequented by those who were both wealthy and worthy of society reporting. The author Daniel Okrent writes that the diners at the Rainbow Room were representative of the uncommon, separated from "the masses" by "a price structure that required a trust fund and a dress code that required white tie." Formal dress was required except on Sundays, each meal cost $3.50 (), and the restaurant even had an exclusive bank of elevators from the lobby. Dinners stretched from 6:30 p.m. to 2 a.m. the next day. In contrast, the Rainbow Grill across the hall had a "black tie" dress code with "white linen acceptable in the summer." The Rainbow Grill, which opened in 1935, was a somewhat less expensive restaurant with an à la carte menu and its own celebrations on major holidays.
