The humble hot dog is getting a rebuild from four different angles thanks to Sonic. The nation's largest chain of drive-in restaurants is unveiling a line of four Premium Beef Hot Dogs in what the Rachel Ray Show has declared is the "Year of the Hot Dog."

This American food staple has long been the domain of ballparks and street vendors, but the average dog has been evolving as of late. Gourmet hot dog restaurants are popping up across the country and experimenting with new flavor combinations.

Now Sonic has added four new Premium Beef Hot Dogs to its menu.

"Sonic's new Premium Beef Hot Dogs have an amazing combination of fresh toppings that create a variety of flavor experiences," says Danielle Vona, chief marketing officer for Sonic. "Our Coney has been a favorite with customers for years and the new hot dogs are the perfect option for lunch, dinner, or an afternoon snack."  

The new Premium Beef Hot Dogs are made with 100 percent pure beef and available in four flavor experiences.

The Chicago Dog is a grilled beef hot dog with pickle, relish, tomatoes, hot peppers, chopped onions, celery salt, and mustard in a soft, warm poppy seed bun.

The New York Dog is a grilled beef hot dog with spicy mustard, grilled onions, and crunchy sauerkraut in a soft, warm bakery bun.

The All-American Dog is a grilled beef hot dog with ketchup, mustard, relish, and chopped onions on a soft, warm bakery bun.

And finally, the Chili Cheese Coney is a grilled beef hot dog with warm chili and shredded Cheddar cheese in a warm, toasted, specialty hot dog bun.

Guests can try any of the new Premium Beef Hot Dogs for $1.99 each, plus tax.
