Portillo's celebrating anniversary with 55-cent slices of cake

MILWAUKEE (CBS 58) -- In honor of their 55th anniversary, Portillo's is selling slices of their Famous Chocolate Cake for 55 cents with the purchase of an entree. 

Portillo's was founded in 1963 in Villa Park, IL near Chicago and is known for Chicago-style hotdogs and Italian beef sandwiches. The company now operates more than 50 locations across several states, including restaurants in Brookfield and Greenfield. 

To receive a 55-cent cake slice, customers must also purchase an entrée (sandwich, hot dog, entrée salad or ribs). The 55-cent cake promotion is only available on April 4 for dine-in or drive-thru customers and does not apply to online, delivery or catering orders.

The special offer is available at all restaurant locations, while supplies last.
