I came in to the bar section of Quinn's and a friend and I sat at their bar doing drinks and food. We left feeling satisfied but I'm unlikely to make this a frequent drinking spot, I had a gift card of some sort to use up and if that wasn't the case I would feel pretty ripped off since their prices are very steep for a simple beer and food item. It is definitely priced to be a hotel bar than a standalone pub.
There was a drunk or just a very strange guy hanging around a certain corner of the bar who was muttering to himself and just breaking stuff like lamps and things hanging from the wall. It was completely random I felt bad for the staff that had to deal with him but no lasting harm was done. It did add a certain unforgettable memory to the experience.
But the staff were very friendly, the food was good and there were certainly a very well stocked bar. If you get the chance to splurge a little for a better than average pub I would definitely recommend Quinn's but for the casual diner/drinker there are certainly similar experiences to be had in the city for better prices.
