The Dunes had the Sultan's Table and Dome of the Sea,

El Rancho Vegas had the Opera House (Theater Restaurant)

Horseshoe had the Sombrero Room (Mexican food)

El Morocco had Jack Dennison's Copper Cart

Desert Inn had the Monte Carlo and the Painted Desert Room

Last Frontier had the Carrillo Room and Ramona Room ("Meeting Place of the Stars")

Golden Nugget had Lillie Langtry's

Harolds Club had the Rose Room

New Frontier had the Venus Room

Royal Nevada had the Crown Room

Sahara had the Congo Room

Sands had the Copa Room

The Mint had the Ambassador Room and Top of the Mint

Hacienda had Garden Room (buffet), the Palm Room (open 24 hours...from eggs to juicy steaks), and Charcoal Room (gourmet dining)

The Flamingo had the Terrace Room

Tropicana had the Brazilian Room

most of these names came from our old menus...a few of them don't go back as far as the 50's and 60's (such as Lillie Langtry's), others might be Rooms that had dinner shows (such as the Copa Room)

hope this helps!
