Smash Cow

You'll find Smash Cow tucked into Unit H5 at Lock, right there in Castle Quay shopping centre on Castle Street. It's the kind of spot that doesn't need much faffing about—they've nailed the fundamentals of a brilliant burger. The smash technique means those patties hit the griddle hard, getting you that proper crust and caramelisation that makes the difference between a decent burger and one worth talking about. It's casual, quick, and the sort of place you'd genuinely pop into on a weeknight without overthinking it.
