I'm always enticed by the wide variety of Ian's specialty pizzas, and I've never been let down. On top of that, their traditional pizzas (pepperoni, sausage, you know, the standards) are spot on as well. I've only ever by the slice at Ian's, but you can also order an entire pie.
While the pizza is great, the staff is fantastic. They're always very friendly and willing to tell you what is on each of the specialty pizzas.
Ian's is great for lunch after the farmer's market, and even better after an evening at a bar on the square or along State St. I'm reluctant to give Ian's 5 stars only because, based on taste, I prefer Roman Candle. But for the environment and speed of service, Ian's is 5 stars!
