This came across the Twitter wire yesterday from @jelsas: A two man, twelve pizza tour of Pittsburgh! There's a detailed report on Pop City that includes snippets of the Twitter log from the tour and mustache ratings of each pizzeria. More

To be clear on definitions right off the bat—the "Tomato Pie" we're talking about here is very different from Trenton Tomato Pie, or even the Northeast Philly version. In the Tomato Pie Belt that runs roughly from South Philly through the western suburbs of Manayunk , Conshocken and Norristown, it's a square pie that consists only of soft, foccocia-like dough, thick, slow-cooked sauce, herbs and a shake of parm or romano, and is ideally purchased at room temperature at a bakery, not a pizzeria.

The veggie slice ($2.50) at Pizza Rustica in University City is really all about the vegetables. The super-thin, cracker-like crust is merely a vessel for a cast of veggies featuring fresh mushrooms, spinach, artichoke hearts, caramelized onions, sun dried tomatoes, roasted red peppers, and little blobs of sweetly roasted garlic. A bit of crème fraîche mixes in with the mozz, accounting for a base that's a little bit more creamy than cheesy, adding a lightness that matches its veggie-centric toppings. More

Celebre's Pizzaz begins with a medium-thick crust with plenty of good chew and crunch. It's topped off with a layer of the tell-tale American, slices of fresh tomato, a generous scattering of bright yellow and red pickled peppers, and finished off with a good shake of oregano and salt. All together these gooey little slices are salty, spicy, and totally satisfying in a way that honestly has more to do with a hoagie or a grilled cheese and tomato sandwich than a slice of pizza.

Santucci's boasts the city's original square pizza, a Philadelphia area Italian bakery staple. According to local lore, it's a variant of tomato pie. This unique style of pizza begins with a rectangular crust with a height that lies somewhere between thin and Sicilian. More

The Philly 'burbs are a vast reserve of uncharted pizza territory, chock full of neighborhood pizzerias that have been around forever—some just OK, others outstanding—but rarely mentioned outside of a 5 mile radius. Vic & Dean's was recommended as one of the best in the Wayne area. More

We're at a point in pizza history where just about every mid-sized American city has a Neapolitan-style pizzeria. But the Pittsburgh area has had a fantastic one since 1996, when Ron Molinare opened Il Pizzaiolo in Mt. Lebanon. More

Night Market Philadelphia, organized by The Food Trust is a roving gathering of the city's best food trucks and stands that sets up every few months in unique locations. June's special, Philly Beer Week Night Market brought a sneak peak of Nomad Pizza, a wood-fired pizza oven truck with plans to open a brick-and-mortar location in Philly in the fall. More

Looking at Wolf Street Pizza's menu I was intriguied by the "sheet pie" listed separately from the Sicilian and the regular pizza. Thinking it might be similar to the square bakery pizza or tomato pie that's fairly common in Philly, I inquired about the sheet pie, and was told "It's sheet pie. Square." Hoping to discover a sub-variant of an already obscure regional pizza variation, I ordered a "half sheet" ($9.25). For lovers of ridiculous amounts of stretching, oozing, ribbons of sliding mozzerella without the bready crust of a standard sicilian, this is your pie. More

Joe's Pizza rightly calls itself the best kept secret in Center City, Philadelphia. Located on an unremarkable stretch of 16th Street, Joe's has been there for years serving quick, cheap slices to a lunch hour crowd. It's the sort dime-a-dozen pizzeria that you'd walk right past if you've never stopped in for a slice. More
