The restaurant, which is named for the singer, has Sinatra memorabilia and photos of him on display.
Sinatra's daughter Tina said the family had rejected similar plans from 12 restaurateurs. She said they agreed to Wynn's proposal because "he was his friend, and he loves and protects us."
Wynn and Sinatra worked together and were friends in the early '80s, when Sinatra sang for Wynn at the Golden Nugget hotel-casinos in Las Vegas and Atlantic City, N.J. The public caught glimpses of the pair's relationship through a series of humorous commercials promoting the Nugget casinos. Wynn was usually the butt of jokes, treated as a bellhop or other low-level employee by Sinatra.
