SAINT-GILLES. This atmospheric restaurant, located in a converted sculptor's studio, is perfect for a romantic dinner or an illicit meeting. Set near an ivy-covered courtyard, the restaurant features black walls, and only candlelight and dim recessed lighting offer illumination. Shadowy alcoves provide private seating, and statues scavenged from old churches add character. The food at Amadeus is equally intriguing. House specials include caramelized spare ribs and beef carpaccio, but non-meat eaters love vegetarian lasagna and ricotta and spinach tortellini. Options are both a la carte and prix fixe, and homemade nut bread is served with every meal. On Sundays, Amadeus hosts a well-regarded brunch buffet featuring smoked salmon, eggs, cheese and bread, cereal, juice, and coffee. Smart-casual to trendy attire. Reservations suggested.

LOWER TOWN. This spot has been a citywide favorite since it opened in the early 1900s. The dramatic Art Nouveau decor ­ including stained-glass scenes depicting Shakespeare's famous character, Falstaff ­ remains virtually unchanged. Drop in for a lunch of piping-hot French onion soup, a crispy croque monsieur, a slice of vegetarian quiche, or a fresh omelet. Falstaff also serves affordable light suppers, including hearty Nicoise salads, rabbit stewed in beer, or the national dish, moules et frites (mussels and fries.) Homemade chocolate mousse and fruit tartes are the perfect way to top off a meal. Casual to smart-casual attire. Reservations accepted.

LOWER TOWN. Authentic Belgian beer cuisine is the specialty at this classic cafe, which was originally a stagecoach inn built in the mid-1700s. The simple tiled floor and plain tables suit the country cuisine. Rabbit stewed in beer and a sausage hotpot are among the house specialties. More than 100 artisanal beers are available ­ the owner can help you choose a few to suit your palate and complement your meal. Casual to smart-casual attire. Reservations accepted.

IXELLES. "The Hardware Store" still boasts its original giant clock, wood paneling, and walls of storage drawers ­ designed in gorgeous Art Nouveau style by Victor Horta's students. The place is especially popular with local businesspeople, who pop in regularly for the three-course "What the Bosses are Having" lunch special. House specialties include a seafood platter and oysters; heartier choices include baked ham and duck with lime. The menu changes each week to take advantage of the freshest ingredients, and the house wine is an excellent, crisp Sancerre. Smart-casual to business attire. Reservations suggested.

IXELLES. The cuisine at this minimalist restaurant is as simple and direct as the name itself. Despite having a decided French influence, "Bread and Wine" keeps the focus on natural flavors rather than on rich, traditional sauces that can overwhelm food. The vegetable-heavy menu features dishes like asparagus risotto with seared tuna steak, chicken ravioli with basil and parmesan, and lobster and shrimp lasagna with a light ginger sauce. Vegetarians need not fear ­ the kitchen will prepare suitable meals on request. The wine cellar is extensive, and wines can be ordered by the glass. During summer months, try to score a table on the terrace. Smart-casual attire. Reservations suggested.
