Au Vieux Saint Martin

Still Worth Coming Back To

If you visited Au Vieux Saint Martin once and filed it away as a reliable Grand Sablon lunch stop, a second look is warranted. What holds on return is the consistency; this is a Franco-Belgian bistro that does not try to reinvent itself each season, at the €€€ price point on one of Brussels' most tourist-heavy squares, that reliability is harder to earn than it sounds. The Michelin Plate recognition in both 2024 and 2025 confirms the kitchen is maintaining its standard, the broader Brussels restaurant scene has enough exciting newcomers that a place this established only keeps pulling repeat visitors if it is genuinely delivering.

The Room and the Energy

The Grand Sablon sets the ambient frame before you even walk in. It is a square built for lingering; antique dealers, chocolate shops, weekend market stalls, Au Vieux Saint Martin's position at number 38 puts it at the centre of that rhythm. Inside, the mood is traditional bistro: the kind of room where conversations carry without bouncing off bare concrete, where the noise level is lively but not punishing, where the pace of service signals that a two-hour lunch is entirely acceptable. If you are coming for a working dinner or a quiet anniversary meal, this is not a hushed room, but it is a warm one. The energy is social rather than intimate. For quieter options in Brussels, Eliane operates at a different register.

What to Prioritise on a Return Visit

Under chef Thierry Strauven, the kitchen spans French bistro technique and Belgian classics, a combination that plays well in this neighbourhood, where visitors expect moules and locals expect something with more precision than the average tourist brasserie. On a return visit, the direction to take is further into the Belgian side of the menu rather than the safer French options you may have defaulted to the first time. The kitchen's credibility, validated by consecutive Opinionated About Dining Casual in Europe rankings (ranked #656 in 2024, climbing to #692 in 2025, a sign of growing traction with a demanding peer reviewer set), suggests there is more depth here than a single visit surfaces. That said, the OAD rankings place this firmly in the casual tier, do not arrive expecting the ambition of Comme chez Soi or the tasting-menu format of Bozar Restaurant.

Booking and Timing

This is one of the easier books in Brussels at this quality level. The venue is open seven days a week, 10am to 11pm, which gives real flexibility, a weekday lunch reservation can typically be secured with a few days' notice, even weekend slots are available without the multi-week lead time required at La Villa Lorraine by Yves Mattagne or the city's more demand-heavy tables. The Grand Sablon weekend market (Saturday and Sunday mornings) does pull foot traffic to the square, so if you are combining a market visit with lunch here, plan to arrive as soon as the kitchen opens for service rather than showing up speculatively at peak hours. For groups, the combination of long opening hours and accessible booking makes this a practical anchor for a Brussels day itinerary.

Value and Position in the Brussels Market

At €€€, Au Vieux Saint Martin sits in the middle tier of Brussels dining, above the €€ brasserie circuit (think Aux Armes de Bruxelles) and below the €€€€ fine dining bracket. For the Sablon specifically, that is a strong proposition, you are paying a location premium on this square regardless of where you eat, getting Michelin Plate quality at €€€ within walking distance of the city's leading chocolate and antique shops is a reasonable spend for what you receive. If you want to spend less and stay Belgian, Aux Armes de Bruxelles is the honest budget alternative. If you want to spend more and go modern, Barge or Eliane represent the more progressive end of the city's mid-to-upper range.

The Neighbourhood Anchor Argument

The Grand Sablon has a particular gravitational pull in Brussels, it is the neighbourhood that visitors return to across multiple trips to the city, Au Vieux Saint Martin has settled into the role of its most dependable sit-down option at this quality tier. That is a specific kind of value. Places like Hof van Cleve or Zilte in Antwerp represent Belgian fine dining at its most ambitious and are worth a trip in their own right. Au Vieux Saint Martin is not making that argument. It is making a different and more modest one: that it is the right place on this square, at this price, for a long lunch or an unhurried dinner when you want French-Belgian cooking done competently in a room with genuine character. For Brussels regulars building a rotation, it earns its place in the shortlist, not as a destination in itself, but as the table you return to when the neighbourhood draws you back.

FAQ

Is lunch or dinner better at Au Vieux Saint Martin?

The Grand Sablon is at its finest in daylight, the weekend market context adds atmosphere, a long weekday lunch here is easier to book and easier to pace than a dinner slot when the square gets busier.
