Chez Léon Restaurant Review in Brussels: Menu, Prices, Reservations, and Who It Suits

By Steve Levine · Updated September 6, 2026

Chez Léon is a practical Brussels choice for mussels and fries, Belgian dishes, families, and large groups, though it is not a budget restaurant. Its broad menu also makes it workable for mixed parties, while reservations and group meals require some planning. Located at Rue des Bouchers 18 near the Grand-Place, Chez Léon is a family business serving Brussels and Belgian specialties since 1893, according to Visit Brussels. This review is based on its published menu and booking information, not a first-hand visit.

What is on the menu?

Mussels are the main attraction, but they are not the only option. The current à-la-carte menu includes seafood starters, pasta, fish, Belgian meat dishes, desserts, and beer. A 500 g serving of mussels with chips and a free pils costs €20.65.

Larger mussel pots range from €29.75 to €33.85, depending on the preparation. Non-mussel examples include fish and chips at €21.75, Flemish beef stew at €23.40, and spaghetti Napolitana at €13.50. These published choices make the restaurant easier to consider when some diners want a traditional Belgian meal and others prefer something familiar. Prices come from the official Chez Léon menu.

How much should you expect to spend?

The €20.65 mussel portion is the clearest value comparison because it includes chips and a pils. A full mussel pot costs roughly €9 to €13 more, while the listed fish and meat dishes sit above €20. A diner choosing the €13.50 spaghetti has a lower-cost main-course option.

Families also have a fixed €9.50 children's menu, with a choice of omelette, chicken, spaghetti Bolognese, or mussels and fries, plus dessert and a lollipop. Treat these figures as planning prices rather than guaranteed quotes. Chez Léon's booking terms say menu prices may change with raw-material market prices, so groups should reconfirm the total before committing.

Who does Chez Léon suit?

Chez Léon most clearly suits visitors who want mussels and fries close to the Grand-Place. It also works for families and mixed parties because the menu extends beyond shellfish. The children's menu gives younger diners four distinct main-course choices.

Adults who do not want mussels can choose options such as beef stew, fish and chips, or pasta. For organized groups, the restaurant documents vegetarian and vegan set menus and says a halal menu is available on request in its 2026 group brochure. That evidence applies specifically to group arrangements, so individual diners should ask what suitable à-la-carte dishes are available before visiting.

Is it suitable for large groups?

Large parties are a particular strength on paper. Chez Léon states that it has 420 seats across nine buildings, plus air-conditioned banquet rooms accommodating 15 to 230 people.

Group arrangements come with firm conditions: The shared-menu requirement deserves attention when guests have different diets. Ask about the vegetarian, vegan, or halal arrangements before selecting the group menu, rather than trying to adjust individual meals on arrival.

A group must have at least 15 people.
Everyone must use one shared menu.
The restaurant needs the menu choice three days in advance.
A booking is valid only after the restaurant confirms it.

How do reservations work?

Diners can request a reservation online or call +32 2 511 14 15; the official contact page provides both options. A request should not be treated as a confirmed table until the restaurant accepts it.

For a straightforward booking, provide the date, time, party size, and contact details. Groups should also state dietary needs, request an updated price, choose the shared menu, and obtain written confirmation.
