I was up there a few months back at a Metallica concert with a few lads, we only managed to hit 2 or 3 pubs.
The Crown bar[/url:hzllje8k]
Nice place, very touristic and jammed. They had 3 Whitewater casks on when we were there; Belfast ale, Clothworthy Dobbin and Crown glory. Very tasty cask beer but a little bit too bustly to enjoy. No where to sit. Worth a visit though.

Enjoyed this pub, quieter afair. Nice staff and a few nice beers on draught and cask. Much less busy than the Crown. When we were there they had 2 casks, Halt by Hilden and Mollys Chocolate Stout as well. They also had Belfast black and Kostritzer on draught as well as a few others. Some Whitewater bottles also in the fridge. Def worth a visit.
Also went to the Duke of York on the walk back. Nice pub, but standard afair drinks wise, bottled Guinness being my drink of choice.
