This off licence has loads of bottle conditioned ale, some lager and a fair bit of cider. Wykeham wines are sold too.
It's all a bit pricey though - the bottles are all around £2.50, but they do good stuff that's unique to this shop in the area.
The brewery museum is OK. If one of the guys behind the till talks you through it, it's interesting. Both guys are helpful & talkative. One is the brewer of Suthwyke Ales and the other appears to own the shop.
The pub next door is good too. They have some good real ale and very reasonable food. Loads of navy memorabilia on the walls, especially US Navy stuff. Worth a visit.
