Beloved downtown seafood spot serving sizzling fish pans and hearty portions; stellar fish with occasional slow or uneven service—book ahead and go for the char and plokkfiskur.
Messinn delivers exceptional seafood quality—the arctic char and plokkfiskur are genuinely special—and occupies a beloved spot in Reykjavík's dining scene with strong destination appeal for travelers. However, quality varies noticeably, with oversalting and weak lobster soup undermining reliability, while service becomes stretched during busy hours. The grade reflects a restaurant that excels at its core strength but lacks the consistency needed for higher recognition.
The room feels cozy and bustling with pans arriving at the table still sizzling, the kind of place where people lean in and share. One diner summed it up: "The char and plokkfiskur were something special." Service warmth varies by night, but the vibe is warm and local right in the city center. The cooking leans classic Icelandic seafood with a modern gloss—rich, creamy sauces balanced by lemon and tomatoes rather than theatrics. Expect shareable fish pans, hearty portions, and straightforward flavors. The char with honey and almonds, wolffish, and plokkfiskur are the hits; the lobster soup and seafood pasta draw mixed reactions, so choose accordingly. For families, this is kid-friendly if you share. The fish burger, simple pasta tweaks, and mild fish pans work for younger eaters, and staff will sometimes modify dishes. There is no kids menu, but generous skillets make splitting easy.
