I am actually near Bermondsey Street now so do know the nearby area fairly well already - but there are places westwards that I haven't got around to exploring properly - e.g. Arancia is a place I keep meaning to try.
Arancia is fab - really good value and nice 'homely' food.
The Spa park is a great facility and I try to go running on the new running track at least once a week. It's also a very sociable place and people have struck up a conversation almost every time I have been there.
