Black Boy Inn Four & Six Restaurant & Bar

You'll find yourself in one of Caernarfon's most characterful spaces when you push through the doors of the Black Boy on Stryd Pedwar a Chwech. This isn't some polished gastropub—it's a proper local's pub with real bones, the kind of place where the bar staff remember your order and the atmosphere shifts naturally from quiet afternoon to buzzing evening. The restaurant side does honest food without pretension, and they've clearly got the formula right, given how consistently busy it gets.
