Chicago loves hot dogs, but do they love Heinz? The ketchup brand would historically say no, and most Chicagoans would agree. Yet, when it comes to hot dogs, Heinz believes they are best topped with the taste of Heinz Ketchup. So, the brand went to the most anti-ketchup-on-your-hot-dog city in the nation, Chicago, to see if taste could win.

It was such was a hit that, today, on National Hot Dog Day, Heinz unveils its signature Chicago Dog Sauce, made with delicious ripe tomatoes and a special blend of spices and flavorings.

Watch the video above to see how much Chicago loved it. Would you be fooled? “Chicago Dog Sauce” is available for a limited time only at the retail price of $5 plus shipping and handling at chicagodogsauce.com.
