Bar 105

You'll find Bar 105 tucked away on Cathays Terrace, in that part of Cardiff where locals actually live rather than just pass through. It's the kind of place where the bartenders take their craft seriously but won't make you feel like an idiot for ordering something simple. The room itself has that comfortable, lived-in feeling—nothing trying too hard, just good cocktails, decent company, and the kind of vibe that makes you want to stay for a second round. Word of mouth has built this place up properly; the 4.6 rating speaks for itself.
