Andrea Bargnani is already asking former Knick Danilo Gallinari about the best Italian restaurants in Manhattan. Bargnani, whose trade from the Raptors will become official Wednesday, is flying in from Rome tomorrow to meet with Knicks brass.

Bargnani and Gallinari, from Milan, are close former Italian National Team members. Gallinari is giving Bargnani a lot of advice.

“We are very good friends,’’ Gallinari said in an email to The Post. “He’s a great guy. He loves to work and he likes New York a lot. He’s very excited. I think he will be good in New York.’’

Clearly, Bargnani, the No. 1 pick in 2007, needed a change of scenery and won’t have the burden of living up to his draft selection. Bargnani, who had an injury-wracked 35-game season, seemingly is healthy and is scheduled to participate for Italy’s National Team in the European Championships, which begin Sept. 4. Gallinari is still rehabbing a torn ACL. When the Knicks drafted Gallinari, there were a lot of comparisons between the two Italians, and Gallinari has proven the better pro.

With Gallinari in Denver and Bargnani in New York, the NBA may consider sending those teams to Italy for preseason next year.

“I hope we do,’’ Gallinari said.
