Portillo's, the fast casual restaurant concept known for its menu of Chicago-style favorites, celebrates National Italian Beef Week May 25 - June 2. In honor of the food holiday, Portillo's hopes fans will share the tastiest ways to commemorate the special occasion with their favorite order.

Whether guests enjoy their Famous Italian Beef dry, with extra gravy or dipped; as a regular Italian Beef or Big Beef; with sweet peppers or hot peppers; take it cheesy on a flakey, buttery croissant; or as a combo with char-grilled sausage, Portillo's is celebrating all flavors, sizes and combinations.
