Having seen this place advertised on the inflight magazine on a recent trip home from Australia, I made a mental note to check it out and thankfully I was in the vicinity by chance when The Merry Ploughboy Pub cropped up like a shining beacon along the roadside.
Whilst it can be difficult not to feel like a tourist in your home town - I really appreciated being able to engage my travelling companion in an authentic experience beyond the pubs of Temple Bar, bus tour stops and the like. We were there on a Wednesday and couldn't believe how busy it was for mid-week. Had a couple of beers downstairs before the show upstairs where we were cordially & efficiently seated by a friendly member of staff. Entertainment & dinner were as excellent as I'd hoped. It's been a while since I had stew like that !
I would recommend you book, I was caught off guard thinking mid-week might be quiet, not sure what it would be like at w/ends.
