Checked out this place last week for a coworker's farewell shindig. We got there right as they opened, all 13 or so of us. We got the nice long communal table in the window. Pizzas seemed to take a while to cook, but our initial round of sausage, pepperoni, and Death by Mushroom was well received. I had the mushroom pie, which has a mushroom sauce instead of tomato, and that sauce has Death and Taxes beer in it. Thumbs up all around the table on the flavor. We ordered another veg pie after that, with roasted peppers and balsamic onions. The onions sounded like a great idea but in reality were too sweet; if they'd added salt that would've fixed it for me. The biggest problem was how wet the pepper-onion pizza was. Pi's slices are all NY style: enormous, thin crust, and wet enough that the tips tend to droop and drip so the slices are best folded to be eaten. But that second veggie pie was way (way) too oily, forming puddles on our plates. I didn't try the sausage or pepperoni pizzas, but I heard they were pretty good.
This older thread specifically talks about the pizza not being wet at Pi, so maybe they had an off day:
I liked the interior, all dark wood but with lots of light from the front window, and an open kitchen along one wall as you head back to the restrooms. I particularly liked the small motorcycle tank mounted on a post out front being used as an ashtray.
This would not be a destination pizza spot for me, but for those in the neighborhood I bet it's a popular spot. Perhaps everything you need to know is right in the name: It's really a bar with good pizza, not a pizza place with a good bar. (Though I can't speak for the bar one way or the other--I don't drink.) I do appreciate the fact that their prices are still $3.14 per slice four years after opening. Guess when you name your bar after a mathematical ratio, you're kinda stuck.
