Where to find Scotland’s best seafood. Clue: these places are just metres from the water

The Highlands and Islands are rightly lauded for their superb seafood – but these days it’s not reserved for fine dining and can be found at the simplest waterside shacks and inns

The best oysters of my life arrive on a polystyrene tray, eaten elbow-to-elbow with strangers at a table littered with empty shells and damp paper napkins. We huddle beneath a tarpaulin, sheltering from the fine spray of rain rattling on the roof, the wind whipping around the hulking CalMac ferry moored metres away, and the beady-eyed scavenging gulls.

“Have you tried this? You have to,” says a woman who has driven from Glasgow just to eat here, pressing a rollmop herring into my hand. I take a bite, the thick skin giving way to sweet and salty flesh, juices running down my chin. Elegant dining this is not, but all the better for it. This is Oban Seafood Hut, tucked beside the ferry terminal for boats heading into the Sound of Mull. Diners shuffle around a shared table, listening for order numbers, with plates piled high with langoustines, crab and oysters. It’s cash only. In the back room, a team of women butter thick slices of soft white bread for crab sandwiches, wrapping them in clingfilm without ceremony, to be sold within minutes.
