Ian's Pizza is non-pizza. Don't get me wrong... I love it, but it's not really pizza.
Even though it's non-pizza, Ian's rules at the pizza-by-the-slice concept. The slices are big (expensive nowadays, but big), they have crowd control in place (necessary in Madison at 2:30 a.m.) and the employees are really patient when your drunk self can't choose between mac 'n' cheese or chicken quesadilla pizza.
When I am craving their buffalo chicken or that one with olive tapenade as the sauce, I'm glad Mesa Pizza in Minneapolis is around to stand in for Ian's. Problem is that it tastes the same, but it's not the same in my heart...
