The Claddagh Ring is the place to be if you want to have a laugh and drink until the early hours of the morning. It's a large pub that is seperated into two sections: One has the band and a dancefloor, and the other has standard pop and indie music playing, along with a couple of pool tables and more seating. It stays open until 2am on Fridays and Saturdays but you need to arrive early if you want somewhere to sit.
It gets packed after about 11pm and sometimes the doormen have to turn people away as it often reaches its full capacity. The entry on a Friday and Saturday is £3, though if you get there before nine it's free.
The Claddagh ring has a lot to offer as a pub, and due to its size and late licence it attracts all sorts of people from all over London as well as its loyal regulars. This always makes for an interesting night, and once you've visited it a few times you'll inevitably catch the Claddagh Ring bug.
Definitely worth visiting if you're looking for a relaxed atmosphere, good music and lots of drinking!
