Lakeside Bar, Thamesmead
Southmere Lake Complex 2 Belvedere Road, Thamesmead, London, SE2 9AN
Thamesmead is not known for its transport links, in fact the opposite is true. Pedestrians in particular face Byzantine paths and inaccessible walkways leading nowhere. Your best bet is to get a bus (the numbers change frequently), most likely from Abbey Wood, Plumstead or Woolwich Arsenal overground stations. Alight as close as you can to Southmere Lake and walk from there (bring a map would be wise). Once at the lake, you'll see the Lakeside Centre on the left. Good luck.
