Here’s one for the commuters. The Exchequer bar on exchequer street will give you a free glass of wine if you show your leap card. You have to get a main meal first to qualify for the offer.
So, if you’re looking for a bite to eat in a really good gastro pub and a drink, you can pretty much knock €6 or so off your bill by using your leap card.
They have an early bird offer from 12-10pm Mon-thurs, and Fri 12-7, which gives you 2 courses for €22. Why not match it up with that? Menu link.
