Costa Coffee

You know that stretch between Trinity College and the old Parliament building where every second person looks lost with a map? Right there sits this Costa branch, doing exactly what you'd expect - decent coffee that won't disappoint visiting relatives or your own caffeine needs between meetings on College Green. The location means it's constantly buzzing with a proper mix of tourists figuring out where Temple Bar actually starts, students grabbing something before lectures, and office workers from nearby who can't be bothered walking further for their flat white. It's nothing revolutionary, but the staff keep things moving efficiently even when there's a queue out the door during lunch. Sometimes reliable beats adventurous when you've got twenty minutes between appointments and need something that won't let you down.
