I like Nathan F.'s comment on the Lowell disclaimer. I totally agree - but for this area, it's possibly the tastiest pizza in town.
Stretchy, chewy, tasty mozarella, sweet sauce, and an almost pastry-like crust that is always thoroughly cooked - no "doughy surprise" in there.
And still, the crust is very crispy considering it's of the hand-tossed variety.
No refills on the $1.05 small sodas, though, is a bummer. And no public restrooms. Yes, it's kind of a dive, but what pizza place isn't? Plus at $1.25 for a slice of cheese pizza, you can't go wrong. Heck, have two.
The pepperoni tastes great as well - didn't try any other toppings. If you're lucky, yoou'll get your slice in about 2 minutes. If they need to make one from scratch, figure 10 minutes. They also have a good variety of subs, like any pizza joint should.
Open till 11 pm.
