Nancy's deep dish pizza is also good:

You can get Malnati's deep dish frozen to take home from their stores, and I've seen it at Sunset Foods. We tried it once or twice and liked it. You do have to let it defrost a day in the refrigerator, though, before cooking; it doesn't turn out as well if you try to go straight from freezer to oven.
As for the frozen, grocery-store versions of Chicago pizzas, I like Home Run Inn. But one of the chains has a nice pizza of its own, which one is that ... oh, Connie's, I like that. Is that a Jewel store brand? Not that it's such great pizza; maybe it's just that it reminds me of my mother. And you can't beat the price. Well, yes you can, if you buy Tombstone, but that's too cardboardy a crust for my taste.
