Aura Brasserie & Bar

You're walking into one of Cardiff Bay's most characterful buildings—the Coal Exchange, where the first atom was split back in 1938—and Aura's the sort of place that respects that history without making a song and dance about it. The dining room's got that upscale-but-not-stuffy energy: decent spacing between tables, proper lighting, and staff who actually know what they're talking about. It's where you'll find locals celebrating something worth celebrating, or just settling in for an evening where the food and drink actually justify the prices. The menu's contemporary British without the pretension—expect solid technique and ingredient quality that makes sense.
