If you're in Thessaloniki during the September Trade Fair, you may want to take in some of the exhibits. Notices of special exhibitions or events are usually posted throughout the city. If you're interested in the contemporary Greek art scene, stop in at the sleek modern building housing the Macedonian Museum of Contemporary Art (tel. 2310/240-002; www.mmca.org.gr). The museum has frequent special exhibits, as well as a good cafe and shop.
