Castle Tea Rooms

You'll find this no-frills spot just off O'Connell Street, where the morning queue of office workers and hospital staff tells you everything you need to know about the quality. The breakfast rolls are proper – none of that artisanal sourdough nonsense, just good white bread stuffed with crispy rashers and black pudding that'll set you right for the day. The coffee's grand too, nothing fancy but reliably strong. The interior hasn't changed much in years, and that's exactly how the regulars like it. Staff know their customers by name and your order by heart if you're a regular. It's the sort of place where you can grab a quick bite before work or settle in with the paper for a proper fry-up, and nobody's rushing you out the door for the next sitting.
