"Consumer Reports" rated Portillo's as having the best sub sandwich nationally so I had to try it. They are a Chicago eatery serving hot dogs and Italian Beef sandwiches. I have tried both the hot dogs and Italian Beef and both were excellent. I added a slice of Mozzarella cheese and asked for my sub to be "dunked" so it would be extra juicy. Took my grandson on my second visit and he loved the atmosphere and the tasty Italian Beef sandwich. I will be back many times.
