Chez Léon is a Brussels institution at Rue des Bouchers 18, on the busy restaurant street in the Ilot Sacré just off the Grand Place. The restaurant dates from 1893 and is one of the longest-established names in Belgian mussel cooking, serving Belgian and seafood dishes to a mix of tourists, families and locals. Mains cost about €18-34, in the mid-range for the centre of Brussels. The signature is moules-frites, a pot of mussels served in a variety of styles, such as the classic white wine and celery preparation, with a cone or plate of fries on the side. The menu also carries other Belgian staples, including waterzooi, the creamy Flemish stew, and steak tartare. Fries are a point of pride and are generally reliable, which helps explain the restaurant's long reputation. Mussels are a seasonal product in Belgium, with the traditional season running through the months with an R, and visitors should expect the best quality in autumn and winter. The dining room is large, bustling and informal, with a brasserie character and a steady flow of customers. Noise levels are high at peak times and the room suits groups and families more than intimate dinners. Rue des Bouchers is heavily touristic, and Chez Léon is the best known of the street's restaurants, so it can be busy at lunch and dinner. The restaurant is open daily for lunch and dinner and accepts reservations for groups, which is useful for parties and for weekends when walk-in waits can build. Individual diners and couples are often seated without a booking outside peak hours. As on many streets near the Grand Place, prices are higher than in neighbourhood restaurants, so visitors seeking cheaper mussels may find better value away from the centre, though Chez Léon remains a dependable first meal for visitors wanting the classic Belgian pairing.
