Anyone that has spent any amount of time in Chicago or its surrounding suburbs knows about Portillo's.  These folks will not look to Yelp for a recommendation.  The Portillo's beef is legendary.  \n\nFor those not accustomed to Portillo's this is the place to go for a true Italian beef.  I've had a few out here.  With the exception of Dazzo's Dog House I have not been impressed.  Portillo's delivers the goods.  You can also get Chicago dogs, Italian sausage, burgers, chicken sandwiches, catering, shakes, malts and killer fries.  \n\nThe restaurant is large and will accommodate a lot of people even with the hoards flocking to a new restaurant. \n\nFor my money you cannot beat the beef sandwich dipped with mozzarella.  It's my standard order.
