NEW YORK -- Burger King wants to lure customers this summer with a barbecue party -- and a bacon sundae.

The world's second-biggest hamburger chain on Thursday is launching several pork, beef and chicken sandwiches as limited time offers. And for a salty-sweet ending, the company is also offering a bacon sundae -- vanilla soft serve with fudge, caramel, bacon crumbles and a piece of bacon -- that started in Nashville, Tenn., earlier this year.

The decadent treat clocks in at 510 calories, 18 grams of fat and 61 grams of sugar.

The limited time offers are the latest push to win back customers with a revived menu and reverse sliding market share, an effort started soon after the company was taken private by the private equity firm 3G Capital in late 2010.
