APizza

Tasty wild mushroom slices at Safeco field, plus (drumroll…) expensive beer!
Way better than the «high cheese» pizza elsewhere in the stadium, which has something like a pound of heart-​clogging cheese on each slice.
Plus any slice that features mushrooms is a good thing in my book

First, this is no way anything like a New Haven style pizza. Granted, it’s the west coast and this is the ballpark version, but this isn’t even close.
I’m still giving it 3 stars though because at $ 7.50 (which would normally be insane for a slice of pizza, but for a ballpark is only a little bit crazy), it’s actually a great deal because even though I didn’t actually weigh it, I’m 94% sure that slice weighed at least 3.7 pounds, which was obviously very filling and prevented me from spending another $ 742 on additional food and booze (okay, I still had another beer, but was relatively sober afterward, which always equates to more savings, except that I’m still out several hours later, which, mostly negates that, run on sentence, comma abuse).
Also, it tasted ok. Better than most ballpark pizza.

If you are looking for New York style pizza this is as close as we have found in Seattle. The crust is thin on the bottom with a nice edge. The sauce is flavorful, and there is plenty of cheese. We will be going to another ball game just for the pizza.

You’re in the ballpark, and you want to eat good food. This is a good slice of pizza — not awesome, not nouvelle-​gourmet, and it’s not going to bring back memories of walks in Naples or of Famous Ray’s. It’s a good slice of a basic snack food — decent dough, good toppings, it is as good as it gets while standing up!
The ballpark’s best salad is here, too — it’s a Caesar, and it’s not fabulous, but it’s green and satisfying enough for stadium food.

My favorite concession stand at Safeco! APizza has giant slices of good pizza for $ 5 and they might be the only place in the Bullpen that has Coors Light on tap. The crust is thin and gets a nice smokey char underneath from the oven, the cheese is plentiful, the sauce is light & tasty, and it all folds together for easy to eat goodness. A great addition to Safeco!
Obviously, if this place existing outside of Safeco it would be average pizza way overpriced, but relative to other offerings at the stadium it’s my favorite.
