Chromium came to Nassau St. with full force late Monday afternoon when Andy’s Diner was trucked to town and moved into position about a block from the University Library. Subject of a long controversy cen tering around the efforts of “Opera tion Nassau” to keep the architecture of Princeton conforming to the tradi tional pattern, the diner is built of chromium with red stripes on the out side. Its interior is salmon pink and blue tile with stools and booths of salmon pink leather. According to its owner, Andrew Alvarez, it is “one of the best diners you can buy in this country today.” Replacing a smaller and older eat ing place, the modern diner is 15 feet wide and 40 feet deep. It was built by the Kullman Dining Car Manu facturing Company of Harrison, N. J. Alvarez has had long experience in the restaurant business. He told of having operated a diner in the present location for the last nine years and previous to that having cooked for other local concerns. No opening date for the new diner was disclosed. “Another week or two or three. I don’t know,” was Alvarez’s only comment.
