Mer du

rooftop · Modern Mer du Nord is the central Brussels rooftop that has, over the past three years, quietly become the city's most reliable mid-tier serious-drinks terrace. The room sits above the Mer du Nord fishmonger's wider operation and uses that pedigree directly — the food programme is built around the kitchen's seafood relationships, and the cocktail menu leans into bright, citrus-forward modern classics designed to drink alongside North Sea oysters and small plates.

The terrace itself is loosely organised and faces west across the lower town, with the post-pandemic shelter system extending the season meaningfully. The wine list is unusually deep on natural-leaning Belgian and Loire producers, the cocktail technical floor is consistent across two summers of return visits, and the team's commitment to the food-and-drink integration is the most fully realised on this list. It earns the top slot for that integration rather than for view drama.
