If this deal goes through, I view Nagel's local competition as Tinto's, Connecticut Muffin and Richol Bakery.
Nostrand is rapidly getting lots of new options.
One could hope that would be true of pizza.
However Papa johns and Dominos have made large inroads.
The old rules (prefences and means) seem to no longer be so strong that the weak can not survive.
Nagles seem to be the choice of private college, liberal arts graduates.
They seem unlikely to eat a lot of Dominos.
