Portillo's is offering a special way for everyone to take part in the chain's 55th birthday. It will offer pieces of its famous chocolate cake for only 55 cents each!
The deal will last only on the day of the restaurant chain's birthday, Wednesday, April 4.
The offer is not valid on online orders.
The Chicago-area chain opened a Greenfield restaurant last year after the successful launch of the state's first location in Brookfield.
