Glass Nickel serves the best damn pizza in Madison. This place is pretty far from the center of town, and the price of a pie is a little higher than normal, but if you're willing to suffer through that, there's no reason you should order anything aside from Glass Nickel.
The best thing about Glass Nickel is that there is a massive variety of specialty pizzas to pick from, and that all the different varieties are simply amazing. I have trouble deciding which one to get every single time.
But of the many kinds, the chicken alfredo stands out as my favorite kind of pizza here so far. Instead of tomato sauce, you get a sweet, creamy alfredo, and it's topped with fresh chicken cooked to that consistency where it's a little black and crisp on the outside, and soft and flavorful on the inside. The mushrooms have a strong and noticeable punch, which is a great breather from all the floppy tasteless mushrooms you'll get on any other pizza. Add a little fresh garlic and spinach to the mix, and you get the perfect novelty pizza.
Also definitely worth a try is their fetalicious, which in many ways resembles your traditional pizza while still offering a unique twist. It comes with all your usual toppings - onion, tomato, mushroom, and then they really zest it up with baked feta cheese and spinach. The feta and spinach make for a great combination that adds a kick without robbing you of the familiar, comforting taste of a good cheese pizza.
Above all, the quality of the ingredients they're using is what makes all their different pizzas taste so good. You know your toppings are going to be fresh when you order from here.
