On a Wednesday in early April 2018, starting at about 21:00, the pub Ryan's at Camden Street in Dublin was tightly packed with young local party-goers, all dressed properly for the occasion. The queue in front of the pub was very long. According to the Facebook page of Ryan's, there was live music (The Buggy Boys was playing).
Oddly enough, the day after (Thursday night) at about the same time there was no crowd there, and the bar (and the entire surrounding streets) looked almost empty, even though everything was open.
On the second day after (Friday night) at about the same time there was no crowd there, and the bar (and the entire surrounding streets) looked almost empty, even though everything was open. I also checked out the Temple Bar and O'Connell Street area, and although there were many crowded pubs and clubs there (some with live music), the liveliness, the vibe and the elegant attire (clothes, shoes, makeup, hairstyle) of partygoers I've noticed on Wednesday night was completely missing.
What is the reason that a Wednesday night in that area of Dublin and that bar in particular is much more lively than a Thursday night or Friday night?
I'm asking this as a tourist without any local clubbing or nightlife experience in Dublin.
