Leaving Monkfish to his devices that sounds like a good night and a good way to actually get to have a laugh with the people at your stag.
I'd mine in Ennistymon, there's only one street with a whole glut of pubs on it and we visited them all. We were staying in the Falls hotel (2 minute walk away) and we had a scream until someone suggested going to the local nightclub (which is actually in the Falls and was a case study in 6-toed mutantism) and split the posse on us.
Worth pointing out -the age range at mine would've been the same as that GH is describing and, other than casually viewing the menu, the vast majority of them wouldn't have been looking to score skirt in the club anyway.
Mercifully anyway there was a residents late bar in the Falls so we all hooked up again later on but the nightclub thing was a blot on the night. It just knocked a couple of hours out of it on us.
