I tried a $1,000 steak at the Fontainebleau Las Vegas hotel. It was the ultimate Sin City dining experience.

The $1,000 Beef Case at Papi Steak, the celebrity-loved restaurant at Fontainebleau Las Vegas.

Within minutes of finding our table at Papi Steak, the flashy Miami transplant at the equally flashy Fontainebleau Las Vegas, an EDM song blasts from the speakers. Our server politely excuses himself, answering the siren call.He joins the wave of waiters and dancers surrounding a nearby table, holding strobe lights and chanting "Hey! Hey! Hey!" in perfect unison. A woman ditches her dinner to join them, waving her napkin around like a tourist in Mykonos. We turn our heads to gawk as a man presents a briefcase that glows gold every time he teases it open.Inside is a 55-ounce Australian purebred wagyu steak. It's branded right then and there, a plume of smoke rising above diners' heads like a new pope being announced at the Vatican.This is the $1,000 Beef Case, and I was about to try it.
