Shana asks a very good question about food service in galleries vis a vis visitor comfort. Galleries are not the space for food service. Cafes or cafe areas (food carts) should be always delineated from exhibition areas. Sorry if my discussion caused this concern, but I feel that all such visitor courtesies be held in proper areas which do not endanger objects. Think about the cafe at the Nat. Gal. of Art (DC) in old bldg. Central, visible and accessible, but not in the exhibition design. Hopes this clarifies this thread of the discussion. Tom B. Columbus
