O’Neill’s Trinity Street is an Irish pub and food venue at 20-21 Trinity Street in central Cardiff. It combines an informal daytime pub with a livelier setting for sport, music and nights out. Breakfast, lunch and later meals make it possible to visit well before the evening atmosphere builds.
The main menu focuses on generous pub food. Stacked burgers, fish and chips, pizzas and comforting classics sit alongside salads and balanced bowls. Smaller plates, wings and sharers make the format practical for groups watching a match or meeting for drinks.
Live sport is a major part of the venue, supported by music and regular events. Bookable tables give groups a way to plan around prominent fixtures, while walk-in visits remain part of the pub’s casual character. Breakfast and weekday offers provide quieter alternatives to the busier evening sessions.
Beer and other pub drinks naturally support the food, with collection and delivery available for selected dishes. Vegetarian and vegan filters are provided on the current menus. Anyone with allergies or a medical dietary requirement should use the venue’s allergen information and speak with staff before ordering.
