The Tastes 29 Diner is comprised of a prefabricated section containing a restaurant and grill area measuring forty by sixteen feet, and a built-on-site shed rear addition housing the kitchen, an office and a storage area measuring forty by eighteen feet. Both cells have their own full basements with poured concrete floors. The rear kitchen is constructed in a utilitarian fashion with cinderblocks that make up the entire wall from basement to roof. The restaurant section rests on a below-ground cinderblock basement topped by brick where the foundation is visible above the surface.
The sub-floor material in the restaurant and rear kitchen is wood. The factory-built section is supported immediately underneath the sub-floor by closely spaced small I-beams that run crosswise. Each beam is marked "BETHLEHEM STEEL." This support system was most likely constructed in the factory. The major load-bearing support, constructed on site is comprised of a cradle of four large I-beams resting on four vertical steel piers. These large beams bear the trademark "PHOENIX USA." Two I-beams run lengthwise making contact with and supporting the small I-beams. The weight is further distributed on two crosswise I-beams that are welded into vertical steel piers. In plan the cradle resembles an elongated pound sign with piers bracing the beam crossover points. The lengthwise beams are tied into and are visible on the exterior brick foundation at both the east and west ends.
The basement below the restaurant section has a below-grade entry on the east side of the building that is flanked by a casement window. The window has been sealed from the inside by masonry-fast cinderblocks. Access to the door is gained by descending poured concrete stairs.
