The Erskine Arms, tucked into a corner of the walled town near the castle, is one of the more characterful pubs in Conwy — a low-ceilinged traditional Welsh pub with a real fire in winter and a reasonable selection of ales. It attracts a mix of locals and visitors, which keeps it from feeling like a tourist trap.
The food is straightforward pub fare — nothing to travel for, but perfectly adequate if you want something after the castle. The main reason to be here is for a quiet pint in a room that feels genuinely old. In summer, the outdoor seating fills up with people who have just done the town walls and are enjoying the view.
