Seem to have fairly good prices and range here - always get Bombay Sapphire Gin cheaper here than anywhere else in town. Always have the same staff there which is nice. There is a supermarket right next door if you need to grab something during the day.
I do not usually buy from here, but now and again they do have some good specials. Plus this shop is right across the road from the Marina, so if you get caught short for a drink while using the barbeque area, you can just nip across the road.
