it's not really crustless, it has a crust of sausage. i still think Lou's has the best deep dish pizza -- and that includes the bread crust -- but now that I'm off bread, the sausage-crust pizza is an excellent alternative to scraping.
i've tried 3 so far: no toppings, pepperoni, green pepper + mushroom. Actually, the no toppings works the best. obviously, lots of sausage in every bite, and that can get a little overwhelming. Two slices more than kicks my butt.
kudos to Lou's for offering it and making it a damn good alternative.
