Ha! Found it. It wasn't on Yelp, but it was in the local paper.

"It was very tense," the diner tells me, "you could hear Amy [Bouzaglo] yelling in the kitchen and Samy [Bouzaglo's husband] was running all over the dining room. Other tables were complaining and people were leaving because they were waiting so long for their food. My partner and I had reservations for 6:45. By 9:30, we still hadn't received our pizza."

Thinking the drama might be part of the show, the diner talked to one of the show's producers, who confirmed that what was happening was real.

Still without pizza, the diner went up to the cash register to talk to Samy, who was arguing with another customer. When Samy saw the diner, he told him his pizza was coming. When the diner answered that Samy had told the diner that an hour ago, Samy responded by saying, "Why don't you go fuck yourself."

And, according to the diner, it wasn't long before Amy came out to see what was happening.

"She was yelling and screaming 'get the fuck out' and saying if we weren't going to pay for our drinks, she was going to call the cops. She called me a 'tough guy' and said, 'You better correct your acting skills if you're trying to get on TV.' The producer said he would pay for our bill and that we should leave."

The diner adds, "The producers told me they had never seen anything like this."
