A small white cabin by the harbour that has been serving lamb-and-pork hot dogs since 1937. The standing order — "eina með öllu" (one with everything) — comes with crispy fried onions, raw white onions, sweet brown mustard, ketchup, and remoulade, all on a steamed bun, for around 700 ISK.
There is almost always a queue and almost no inside; eat standing up by the harbour wall like everyone else. Open late into the night, which makes it a fixture of the weekend Rúntur.
