An open kitchen and a vast, fire-toned wall mural create a feeling of warmth among diners, and a crystal chandelier adds a hint of glitz. But the overall mood at Fred’s Not Here is casual and upbeat, serving as an ideal setting for a pre or post-show feast. The restaurant seats 100 and attracts a fairly constant flow of people, so reservations are certainly recommended. And for patrons combining a visit with a show on King St., the restaurant offers a number of affordable specials worth looking into.
