Mustard on deep dish? Bizarre. Does it work? Apparently, yes, according to the good folks at Portillo’s and Lou Malnati’s Pizzeria, who are teaming up for a new crosstown collaboration: The Chicago Dog Deep Dish.
“At least we didn’t put ketchup on a Chicago-style hot dog!” said Katie Maldonado, a Lou Malnati’s representative. “We knew this would raise eyebrows, but we were committed to staying authentic to the Chicago dog experience and that means mustard.”
The pizza will be available for 30 days (or while supplies last) at Lou Malnati’s full-service restaurants in the Chicago area, Milwaukee and Arizona, and can be ordered for dine-in, carryout or delivery. The pizza, which is only available in the small deep-dish size, will not be available at carryout-only locations.
