HONOLULU - In at least one way Senator Barack Obama's fund-raiser Tuesday night in Hawaii will be just like all the others: supporters had to fork over a big check - tickets cost $2,300 - to rub shoulders with the candidate.

And that's where the similarities end.

In almost every other way - from the dress code to the entertainment - the sold-out event at the luxury Kahala Hotel and Resort - will be a distinctly Hawaiian affair.

Guests will be treated to performances by an award-wining local hula ensemble as well as Kuhi Suganuma, who was crowned Miss Aloha Hula 2008. The musical entertainment includes Willie K, a guitarist who the Honolulu Weekly once described as "a Hawaiian Jimi Hendrix" and Raiatea Helm, a Grammy-nominated Hawaiian female vocalist.

The invitation lists Hawaii's Senators Daniel Inouye, Daniel Akaka as well as Representatives Neil Abercrombie and Mazie Hirono as honorary co-chairs of the event.

On the menu: Hawaiian pupus.

And leave your haute couture at home. The dress code tonight is "Aloha attire," according to the invitation. (In case you're wondering, that means flower-patterned Hawaiian shirts and muumuus are acceptable, even encouraged.)

More than 500 guests are expected at the fund-raiser, and those who contributed at least $10,000 to the Obama campaign and the Democratic National Committee were invited to a V.I.P reception to have their picture taken with Mr. Obama.

The campaign is hoping to collect $1.5. million on Tuesday night. That is more than three-times their original goal and, as the Honolulu Advertiser pointed out today, would exceed the total amount Mr. Obama has raised from residents of Hawaii since he began his presidential campaign.

The private fund-raiser will be only the second - and perhaps last - event on Mr. Obama's official itinerary during his week-long vacation here.

The Illinois senator, who was born in Hawaii, has been keeping a low-key schedule on the island. On Monday, he visited his grandmother, Madelyn Dunham, at her Honolulu apartment for the third time on his trip. Later he watched "The Dark Knight," at a nearby movie theater and ate dinner with his wife, Michelle, his sister, Maya Soetoro-Ng, and a group of friends at an upscale Honolulu restaurant.
