Manzo's on Irving Park & Kedzie is great for pizza for eat in or carry out (I believe they have carry out as well). You can choose from different types of pizza (thin crust, pan, stuffed) and different toppings and combinations. I found that my favorite is the thin crust. There's still enough crust to support the pizza and it's not too crispy. The sauce also has a nice tomato-homemade flavor.
In addition to pizza, the menu is quite extensive, though I haven't had time to venture much beyond the great pizza yet. Give this place a shot if you're in the area!
