I'm not usually one for pubs, but if I were, it's safe to say that McKibbin's would be my spot.
Live music, lots of beer and classic pub fare, it's actually a pretty fun time if you're not jammed in there trying to get a table.
The food is good, the beer is good, the atmosphere is good. Really, it's an all around good vibe, and that's (you guessed it) good.
