Ortega is extending the Cinco de Mayo celebration by officially declaring May 6 as Seis de Mayo. To mark the occasion, the brand will stage taco truck pop-ups in Chicago’s Pioneer Court from 5:30–10:30 a.m. serving 750 breakfast tacos, then in Wrigleyville from 4–7 p.m. serving 1,250 Chicago Taco Dogs.

The Chicago Taco Dog blends a classic Chicago-style hot dog—with mustard, relish, onions, pickle spear and sport peppers—inside an Ortega taco shell topped with Ortega taco sauce. This limited-time mashup was created in collaboration with Celebrity Chef Kelsey Murphy and debuts at the Wrigleyville pop-up.

To drive broader participation, Ortega will run a buy-one-get-one-free promotion on select products May 5-6 at participating retailers. The brand is also launching the Seis 50 recipe series, featuring taco mashups inspired by iconic dishes from each of the 50 states to sustain the fiesta beyond Chicago.
