Following the success of last year’s 55-cent cake slices, Portillos plans to offer slices of its “Famous Chocolate Cake” for 56 cents in honor of its 56th anniversary. YES!!! Customers can get their 56-cent slice on Tuesday, April 9, with the purchase of any sandwich, hot dog, entree salad, pasta or ribs. I’ll see you all in a Portillo’s on April 9th.
