DAY 1 OF THE PIZZA-A-DAY PLAN:
Mangia Pizza (2400 Lake Austin Blvd., and other locations) was founded in 1988 (which is a good thing, because I started graduate school down here a year later) by a guy who quit government work and had fallen in love with stuffed pizza while doing training in Chicago.
Mangia is, of course, the home of the world-famous Mangiazilla. Unfortunately, Mangiazilla itself no longer graces the top of the delivery truck (apparently it kept getting knocked off), although I believe there is still a Mangiazilla atop the Guadalupe location.
Mangia consistently offers an excellent stuffed Chicago-style pizza (it being Austin, it's available with white or wheat crust). I ordered what's called the "Chicago Special," which is sausage, green peppers, mushrooms, and onions, on a white crust. (I also ordered a salad which, despite assurances from the staff that it was "really small," was more than adequate. And rather large, actually.).
Delivery took about forty-five minutes; the crust was firm, not soggy, and had an excellent, rich texture. The pizza was still hot and the ingredients were of good quality -- you could taste each of the toppings in every bite. All in all, an excellent pizza experience. (If you're not a carnivore, their spinach pizza is really good, too.).
Oh, to clarify for those who are not from Chicago: A "deep dish" pizza is a pizza that is made in a dish about two inches deep and has a single layer of crust (on the bottom). A "stuffed" pizza is a form of deep dish pizza, but it has two layers of crust and (for the most part) all the ingredients go in-between, although the tomato sauce (always) goes on top.
