This is not a pub, but certainly one of the best whisky bars I've ever been to (I've not been to any good ones in Scotland though)... All the lovely bottles of whisky lined up above the bar make an impressive sight. I had Caol Ila 12 first followed by Nikka Sendai 12, and my wife had Cragganmore 1987 Distillers Edition. All were great drams, but the latter one was simply exceptional...
