"They're open late and they're not McDonald's. If you crave late night pizza, or you just didn't get a break at work and you get off around 11:30 midnight, and you don't want the usual fast crappy food, Slice Factory is good. You sometimes have to wait a while for your order, if you order something other than a slice of cheese or sausage. If you order directly from them, it's way cheaper than DoorDash or any other food delivery service, and the slices are HUGE. And their salads are also HUGE. I think their best slices are Tropical Barbecue Chicken, Factory Special, and Veggie. (This is not my favorite place for a jumbo slice of sausage pizza; if that's what I crave, I'll go with Anthony's on Cermak if it's before midnight, or DiNico's on Roosevelt after midnight both in Berwyn, too. Don't miss the Nutella bites! They're awesome."
