A number of chains this summer are getting back to burgers with new items. Freddy’s, a Wichita, Kan.-based chain, is actually combining hamburgers and hotdogs in its Freddy’s Burger Dog, a beef hot dog sliced and placed on top of the restaurant’s signature steakburger. Dairy Queen is offering the Sweet Apple BBQ Grillburger. The 4,488-unit chain's new burger includes bacon, onion slices, lettuce, a tomato slice and pepper Jack cheese topped with a sweet barbecue sauce that contains chunks of apple, and it’s served on a home-style bakery bun. Red Robin is the first chain to add super-hot ghost peppers to its nationwide menu with two spicy burger options: The Fiery Ghost and the Cry Baby. I'd like to see Joey Chestnut eat 68 of those in 10 minutes.
