Chef Emeril Lagasse's take on the grand American steakhouse. Delmonico Steakhouse brings back a time when lunch was an event, cocktail hour was not to be missed and dinner with friends was a celebration. At Delmonico Steakhouse, we remember. Located in The Venetian Resort Hotel Casino in Las Vegas, Delmonico Steakhouse takes its name from the legendary, century-old New Orleans institution, Delmonico Restaurant and Bar.
