Some clubs and bars don’t welcome those who are too casually dressed (battered sneakers or runners in particular seem to annoy doormen) so make a bit of an effort. Bars typically serve until about 23:00 Mon-Wed and about 24:00 Thurs-Sat. Late bars and clubs usually serve until 02.30, though if you’re a resident in a hotel you can drink in the residential bar as late as you want (within reason, of course).
Indie music venues
There’s a veritable hub of bars for music fans, some of which are live music venues linked with traditional bars.
The good news - Dublin has a great variety of clubs regardless of your music tastes, sexual preference and nightlife habits. The bad news - most have a cover charge, sometimes between €15-20 on weekends. Most of them close (ie stop serving drink) at about 02:30, but some stay open a little later. The mythical lock-in (when the venue closes the shutters and serves drink long after closing time) happens very rarely - we estimate an average three times in a lifetime - but it does happen.
Not quite pubs, not quite clubs, but essential in a country with such archaic licensing laws, late bars serve much the same purpose as nightclubs (dancefloor, late license...) but are essentially pubs that don’t charge you in (at least before a certain time) but stay open late. They’re often, we think, preferable to clubs and draw a marginally older crowd.
