At what casino did Joey from "Friends" work while waiting to make his movie?

Joey from "Friends" worked at Caesar's Palace while waiting for his movie to resume production.

In the fifth-season storyline set around Las Vegas, Joey travels there expecting to make a film, but the production is put on hold because it lacks funding. To earn money, he takes a temporary job at the famous casino-hotel, appearing as a Roman gladiator or centurion.

The job is one of Joey Tribbiani's many unusual ways of getting by between acting roles. His friends discover him working there during the two-part episode commonly known as "The One in Vegas," where the group visits Caesar's Palace and Joey tries to keep his employment secret.

A common mix-up is calling the job a casino dealer or hotel employee. Joey does not deal cards; he performs in costume as part of the property's entertainment. Caesar's Palace is also a hotel and resort, but the question correctly identifies it as the casino where Joey worked.
