Upside Pizza

"After trying Upside’s cheese slice from their new Soho location that’s made with sourdough, we might be ready to say goodbye to Joe’s as our de facto NYC slice recommendation. The dough from Upside is noticeably tangy, the cheese stays put, and there are patches of bubbly caramelized cheese that make us thankful for fire. The square slices shouldn’t be missed, especially their cheese-less Sicilian that’s covered in thin slices of garlic, crisped up basil leaves, and perfectly seasoned tomato sauce that’s zesty and not too sweet." - Carlo Mantuano

"Upside Pizza is expanding into Pomodoro Pizzeria’s old spot in Little Italy." - Erika Adams

"Outsider is a slice cart that someone stuck on the side of the road at Beacon Hill Station, and while they used to bake up fantastic personal pies topped with charred dough bubbles and freshly grated pecorino romano, things have changed since then. It's now a by-the-slice operation that serves pretty lackluster New York-style pizza. Nothing's overwhelmingly terrible about it, but much like slices you'd find at an airport kiosk (you know the ones, with names like "Via Piazza" or "Mamma Mia"), the sauce is overseasoned, there's too much cheese, and the crust doesn't have any flavor or bready chew. If you're in the neighborhood and are desperate for pizza, go to Bar Del Corso instead." - Aimee Rizzo

A good place to go for a slice with less problematic ownership.
