I'm not surprised by the mixed reviews. One day I took a friend to a very authentic Mexican restaurant. I was delighted. She turned to me and said, ""Taco Bell is WAY better."" And since I spend more time enjoying food than enjoying people, she and I are not friends anymore.
If you're looking for a big chewy circle of doughy bread, slopped with sauce and a layer of cheese a quarter inch thick, do not go to Sweet Home Chicago. Go visit a Little Caesars, or call Domino Hut. This pizza is different, and it all starts at the foundation. The crust here is subtle and plain. Another reviewer in derision compared it to a cracker, and while I disagree with his/her characterization, I don't think it's a bad comparison.
The crust here is a kind of understated vehicle---it's not the show itself, but is what the whole rest of the show rides on. Because it's subtle, it allows you to taste tomato in the sauce, and each of the toppings seems to stand out a little vibrantly. The result is that it doesn't taste like most pizza---an indiscriminate mush of lipids and carbohydrates---but it tastes like flour, tomatoes, peppers, olives, and sausage, all contributing distinctly in a greater whole.
You do tend to wait longer for the food, but it doesn't bother me to have someone take more time to prepare my food. I've never had rude service. And regarding sanitary concerns, the Draper location has large windows into the kitchen, and I've never seen anything that alarmed or worried me.
