As the Four Corners of Delmar evolve over time, Keystone Builders has done its part to significantly improve the long-standing structures that we all remember. This location, at 376 – 378 Delaware Avenue, was fully renovated to accommodate two businesses yet it maintains the familiar outline that faces the street. A pedestrian walkway runs along the right side of the building leading to an outdoor patio at the back. The interior of the Coffee Shop offers a place to relax near a fireplace, especially on a cold winter morning.
