The diner is ten bays wide and three deep, and sits on a brick foundation.

A kitchen wing, built of concrete blocks, connects the diner to the house at 507 Main Street.

The entrances to the diner are at either end, with original stainless steel doors bearing sunburst motifs.

Inside the diner is a full-length marble counter with center staff access, with 18 counter stools, and wooden booths lining the front wall.
