Old Boy in Brussels: A Fire-Driven South-East Asian Grill

Bangkok Roots and a New Direction

Old Boy in Brussels recently completed a four month renovation that reoriented the entire South-East Asian kitchen around live fire. The team spent ten days navigating street stalls and local markets across Bangkok before reopening this Rue de Tenbosch venue. That journey now drives every plate, which Gault&Millau recognizes with a 13.5 rating for its renewed focus on authenticity. Seasonal menus change with daily market arrivals, keeping the grill concept grounded in what is actually fresh.

House Made Curries and Relishes

Sharp nam prik and homemade relishes sit ready to cut through the richness of the charred proteins. Every curry paste travels through the kitchen rather than arriving prepackaged. The dining room encourages sharing small plates while you settle in for either lunch or dinner service. A fixed evening menu appears for larger parties, though individual ordering remains standard for most tables. This South-East Asian grill approach keeps the focus squarely on technique and spice balance.

Open Flames and Flexible Service

An open fire anchors the dining space, echoing the bustling energy of Bangkok street markets. Walk ins remain welcome alongside advance bookings, though weekend visits benefit from early planning. Cancellations can be adjusted without penalty until three p.m., while staff prioritize flexibility over rigid formalities. The result feels less like staged hospitality and more like a neighborhood favorite that earned its stripes.
