TOMORROW IN L.V.

“Iron Chef” superstar Masaharu Morimoto soft opens his Japanese restaurant at MGM Grand in the former space of Shibuya. The contemporary Asian design combines delicate Japanese beauty and elegance with exotic photographs by Yasumichi Morita for a stunning signature touch.

Welcoming diners to the new art of Japanese culinary styles, the famed Food Network personality says: “No Rules. Don’t be afraid to do whatever you want. Cooking doesn’t have to have rules. I don’t like it that way.”

Morimoto made his mark while working for Nobu Matsuhisa in New York. He was scheduled to open his Las Vegas location at The Mirage, but corporate execs moved him to MGM Grand.

It’s wall-to-wall network TV coverage on pre-debate day as Hillary Clinton and Donald Trump prepare to square off in the final showdown moderated by Fox News anchor Chris Wallace at the Thomas & Mack Center. I’ll be broadcasting from the Fox News satellite studio at MGM Grand on Neil Cavuto’s show at 1 p.m. PT.

And it’s the countdown to concerts by The Rolling Stones at T-Mobile Arena on Wednesday and Saturday.
