I'm surprised to see an average of only 4 stars. My family has visited this location 3 times and we have had a great experience each time. I grew up going to the Buffalo Grove location and was thrilled when I heard Lou's was coming. I even waited in line for 2 hours when it opened! They handled the line great, handed out water and samples and the manager came around chatting. It was like a big Chicago reunion! The pizza is perfect, exact replica of what I grew up with. That layer of sausage is so delicious! And make sure to get butter crust! Service was friendly each time and pizza took reasonable amount of time. I recently visited a competitor and was reminded that Lou's really is the best! If you want to try amazing Chicago style pizza, go to Lou's!
