I took some shots of that myself, especially the name. At first I did a double take of that, though I noticed the bar's emblem was a bird with two fish in its mouth (also present in this shot). Not being even remotely an ornithologist, I had no idea at the time that a "shag" was a variant of a cormorant. Which... I suppose means that it is not necessarily the type of bar that the name might initially suggest.
