Whenever we go to CT, we enjoy a trip to Willington pizza. It's a great local place (there are actually two locations now, but we love the original), that has a casual but fun atmosphere (red/white checked tablecloths, local sports memorabilia around). The best thing on their menu, in my humble opinion, is the award winning red potato pizza. It might sound strange, but the potatos, delicious crust and sour cream sauce, all blend to make a wonderful flavor combination! While specialty pizzas are at their best, you can also build your own pie for a very reasonable cost. two people can easily share a small for lunch (for around 8 dollars with one topping)
Reasonable prices, great food.
