And my new favorite out of the best is now Pequod's Pizza in Morton Grove, although there's one in Chicago too. I don't know what's with the logo (a whale with a pair of thong panties on its head), but let me tell you about the joint. It's tiny and it's a little dilapidated.
It reminds me of an establishment I used to frequent in Michigan that had a bar and some little tiny tables and a pool table. You might be able to serve the whole dining room from one spot and it's delightfully and purposefully slightly ramshackle, just so you know what you're getting into.
As for the pizza, it's amazing. The crust is thick and yeasty, crunchy on the outside and chewy on the inside. The tomato sauces manages to be delicious without being sickly sweet; the tomatoes still have a kick. The cheese and pepperoni were delicious if not a bit standard. What Pequod's does that's different is they let the cheese on the edges burn or "carmelize" as they say, which produces a satisfying crunch. Same with the edges of the spicy pepperoni.
If you're in the neighborhood, this is where it's at.
