UPPER TOWN. What could be more chic than drinking in a 1920s train car decorated in Art Nouveau style? The young, hip crowd come to drink Belgian brews and snack on fresh, reasonably priced salads, omelets, and sandwiches. During the balmy months, patrons jockey for a spot on the sunny terrace. Smart-casual to stylish attire.

UPPER TOWN. This spot has been a popular artists' hang-out since it opened in 1846. Local poets and writers-in-residence have jotted their musings on the walls, and the eclectic decorations (everything from antlers to bicycle tires) may help explain some of Magritte's paintings ­ he was a former patron. Drop in to experience for yourself the kitschy hominess that makes it so popular with locals. For the price of a beer, you'll probably make a few new friends. Casual.

LOWER TOWN. This refined brasserie, located across the street from the Brussels Stock Exchange (the Bourse), is filled with well-dressed businesspeople, drinking away a hectic day. In fact, wood paneling and turn-of-the-century decor seem to suit the "suits" that congregate here. Though a wide selection of Belgian beers is available, the house drink is the "half and half," a concoction of white wine and champagne. Smart-casual attire.
