Sources said some of the unhappiness stems from the celebrity investors not being invited to be partners in LAX nightclub at Luxor, which they believed had been agreed upon.

SHOOTING FOR THE STARS

Wolfgang Puck, who opened his sixth Las Vegas restaurant last week, is aiming for the stars: his first-ever Michelin three-star eatery.

During a stop at our table, I asked him if he's considered doing a dream restaurant to crown his career.

"I'd like to do one with about 45 seats, and make it a three-star," he told me during his VIP opening of CUT Steakhouse at the Palazzo.

It would be Puck's ultimate challenge.

Michelin, the world's most prestigious dining guide, had never published a Los Angeles or Las Vegas version until this year. The only three-star rating awarded to a restaurant in either city went to Joel Robuchon's at the MGM Grand.

Puck's next fine dining frontier is likely to be Singapore, where billionaire Sheldon Adelson, owner of The Venetian and he Palazzo, is building Singapore's first casino on a 50-acre waterfront site near the financial district.
