Vice President Biden dropped in to grab lunch for himself and the president at the grand opening of Capriotti's, a Delaware sandwich shop launching its first Washington franchise on Thursday.

The vice president used the occasion to declare that the country's best sub sandwiches came from his home state.

"This is gonna settle once and for all, the best sandwich in America is out of Wilmington, Del. I'm bringing one back for the president. No more of this stuff about Chicago and Philly and New York. This settles it," he said.

Biden ordered three Italian subs and a fourth with turkey, cranberry sauce and stuffing, called the Bobbie. One was destined for presidential adviser Dan Pfeiffer, a fellow Delaware native.

The total was $56.25, but the vice president came up a little short on cash, before an aide came to his rescue.

"I've been going to Capriotti's on Union Street for the last 40 years. I have paid every time I've gone. ... In Delaware, you pay. It's simple," Biden said.

The Washington Nationals' racing presidents mascots were on hand for the launch, but the vice president warned them they might not be welcome at the restaurant's other branches.

"Hey I love you guys. But you know, if you showed up outside of Capriotti's on Union Street, you'd be in trouble. They're all Phillies fans, you know what I mean?" Biden said.

While departing, the vice president was asked if he supports the Senate's move to end the filibuster on presidential nominees.

"Yes, I do," the Senate veteran said.
