A Slice of New York, the now-famous Murrysville pizzeria vaulted into regional conversation by a Barstool One Bite review, has officially landed on the South Side. The new outpost, tucked into the Highline and branded A Slice of New York Squared, is serving slow-fermented sourdough square pies alongside the original shop’s classic New York-style slices as part of a broader shuffle of food tenants.
As reported by Pittsburgh Business Times, the Squared concept opened yesterday, taking over roughly a 700-square-foot window on Carson Street. The outlet also notes that owners Sean and Jessica Jefairjian locked in a nine-year lease extension at their Murrysville flagship so they can run both locations at once instead of choosing between city and suburbs.
Highline Reshuffle And Partners
Burghers Brewing is moving its compact South Side taproom into the former Sly Fox Brewing space at the Highline, clearing the smaller Carson Street window for the new pizza operation, according to Pittsburgh Magazine. Burghers plans to scale up its brewing and kitchen footprint in the larger Highline space, while A Slice of New York Squared leans into a tight, process-heavy pizza program out front.
What Squared Will Serve
Squared is built around rectangular, slow-fermented sourdough pies topped with premium ingredients, per a post highlighted by Patch. The compact window setup points toward grab-and-go service and a focused, high-quality menu rather than a full sit-down dining room.
Back in Murrysville, Sean Jefairjian’s original shop jumped into the spotlight after scoring an 8.2 on Barstool’s "One Bite" scale from Dave Portnoy, a boost that helped the brand reach a much wider audience, CBS Pittsburgh reported. That built-in buzz now follows A Slice of New York Squared straight into Carson Street’s late-night and weekend crowd.
The new Highline additions fit into a broader push to blend breweries, compact kitchens, and nightlife staples along Carson Street, a shift that local outlets say is reshaping the South Side’s restaurant ecosystem, Pittsburgh Magazine notes. For A Slice of New York, the downtown experiment gives the Jefairjians a way to test a city model while keeping their suburban stronghold intact.
Owners say preview events and detailed operating hours will roll out over the next few weeks as the teams ramp up, with the initial menu reportedly kept tight while staff and systems settle in, per Pittsburgh Business Times. If the Murrysville fan base makes the trip, Carson Street may be looking at another pie worth waiting in line for.
