HONOLULU -- Traveling allowed Robert De Niro to celebrate his birthday twice.

De Niro first turned 64 in Melbourne, Australia, on Friday where he attended the grand opening of his latest Nobu restaurant. Then he caught a private jet over the international dateline and had another birthday Friday in Hawaii.

While many his age are thinking about retirement, the Hollywood star seems as busy as ever with his film career and Japanese restaurant chain, which is quickly expanding internationally.

“I have time,” he said on his birthday, sitting in one of the private rooms at his swank Nobu Waikiki restaurant, which opened in May.

Nobu Waikiki, located in the Waikiki Parc Hotel, and Nobu Melbourne are his 18th and 19th, respectively, in the chain, with additional restaurants planned for San Diego and West Hollywood, Calif.

The Nobu chain was a result of De Niro meeting Nobuyuki Matsuhisa at the chef’s first U.S. restaurant in Los Angeles more than 20 years ago.

“I thought the place was great. I told him, ‘If you ever want to open a restaurant in New York, let me know,”’ De Niro said. “A year or two later, he called me, said, ‘I’m interested.”’

Nobu started as a business partnership in 1994 among De Niro, Matsuhisa, Richie Notar and Hollywood producer Meir Teper. The first restaurant opened in New York. The chain now has locations across the world, from Italy to the Bahamas.

De Niro’s latest film is “Stardust.”
