The menu, which was saved from the 1912 sinking by first-class passenger and New York businessman Abraham Lincoln Salomon, sold for a high bid of $88,000 to a private collector during Lion Heart Autographs' online auction.
The New York auction house had earlier expected the menu to sell for up to $70,000.
The menu was one of three items up for auction from the so-called "Money Boat," the Titanic's Lifeboat 1, which carried just five wealthy passengers and seven crew despite being designed to hold up to 40 people.
A printed ticket from the ship's Turkish Baths weighing chair sold for $11,000, while a letter written by survivor Mabel Francatelli, who allegedly paid off the "Money Boat" crew to paddle away from the wreckage instead of pick up survivors, sold for $7,500.
"Today's auction far exceeded our expectations! The Titanic lunch menu sold for $88,000 and the Titanic ticket for $11,000! Thanks to everyone who participated!!!" Lion Heart Autographs said on its Facebook page.
