Well, looks like you've solved it, but if you're making the trip again, you can scoot down either highway 1 to 80, or 151/13/30/380 and then back over to the Coralville 1st avenue exit...backpocket brewery...is <2 minutes off I-80, they serve pizzas. Not deep dish, but stone oven pizzas. Pretty good, had it for lunch today. Good beer too, got a half-gallon of their Dunkel that I'm working on right now. Sounds outta the way, sure, but not too bad compared to a 90 min wait for a deep dish.
Interestingly, I noticed that one of their seasonals (an ESB) was named AIRBHG. I told my wife I should be drinking the **** out of it with that name. Gotta support AIRBHG.
