Duncans has everything you need that involves alcohol. A wide selection of wines, beer, vodka and whisky. You can also buy gifts from here. If your hungry you can pick up some chips or nuts.

All different types of drinks here and quite well priced. They also sell nibbles if you need some! They also have some great little gift ideas. A rather big shop with soft drink as well (gotta have them for your mixers!) Staff are also very helpful in what you need/want/looking for
