Union Station, 800 N. Alameda St., Los Angeles. Built in 1939, this was the last major train station constructed in the U.S. With its tile floor and fanciful roofbeams, its part Mission Revival, part Streamline Moderne. Unfortunately, one of its old restaurant spaces is idle most of the time, but you can eat well on site at Traxx.
