Established way back in 1979, Nick's has certainly been a permanent part of Mount Lebanon's dining landscape, and is likely the preferred purveyor of pizza for area residents. An appropriate analogy would be Brookline's Fiori's or Dormont's Campiti's.
Recently, Kay and I decided to sit down and try Nick's pie for ourselves after traveling past it a dozen times while running errands.
An oddity among its competitors, a Nick's crust is somewhat thin like you'd find in a Big Apple sidewalk special. A crisp exterior hides a somewhat plush interior. A fruity sauce, a freshly-grated mozzarella/provolone (?) blend, fatty bacon bits, and savory black olives finished off what was a tidy, tasty platter of goodness.
The Meatball hoagie fell a tad short with its somewhat dry meatballs, the fine sauce and cheese salvaging the sandwich.
The white-walled interiors are as sparse as the seating, but don't allow that to keep you away. Nick's is quietly serving up some quality pizzas in a modest storefont in a sleepy suburb. It's time the secret fell out of the attic.
