Went to Durty Nellies in Bunratty (county Clare, by Shannon). Was great, but expect lots of tourists.. don’t expect to meet a lot of locals at this pub at least.

Another tip.. I stayed at a nearby BnB.. the owners invited me to go to the pub thats within Bunratty Castle. Its where the locals go- awesome, AUTHENTIC musicians, drinks.. definitely the stereotypical- breaking out in song type of places. :)
