DENVER – Smashburger is launching its Chicago-inspired Windy City burger to its restaurants nationwide from Sept. 26 to Oct. 30. This offering includes Certified Angus Beef, topped with cheddar cheese, onions, lettuce, tomato and mustard on a pretzel roll. The new burgers are priced at $5.99 and $6.99.

"In every market we enter, we take the time to create a unique burger experience for that city that incorporates local taste preferences and our Windy City burger has been particularly successful in its hometown of Chicago," said Tom Ryan, founder and chief concept officer of Smashburger. "We received great feedback from our guests after rolling out our Sin City burger as a national limited time offer last spring, and we're eager to give them another chance to enjoy a local favorite from another city."

Smashburger calls itself the country’s fastest-growing, fast-casual “better burger” restaurant.
