Dibella's Old Fashioned Submarines is a sub sandwich restaurant chain based in Rochester, New York, United States.

It first began as a family-run Italian import store and delicatessen in the city of Rochester.

[1] From there, DiBella's opened additional locations around the Rochester area, then expanded into nearby Buffalo.

In the late 2000s, they started expanding out-of-state, first to the Pittsburgh area, then to parts of Ohio and eastern Michigan.

They have also opened locations more recently in Albany and Syracuse, and in 2012 the company moved into New England, specifically Connecticut and the Hartford / New Haven area.
