Canalside Fish & Chip Shop

You're standing on the canal towpath in Fort Augustus, and you've just grabbed a paper cone of golden chips from this place. It's the sort of spot where you queue with hikers, lock-keepers, and locals who know exactly what they want. The fish is properly battered—crispy outside, flaky within—and the chips are cut thick enough to actually taste of potato. There's no pretence here, no gastro-nonsense, just the kind of honest takeaway food that tastes better when you're eating it by the Caledonian Canal, watching the water lap against the lock gates.
