Frankie & Benny's is part of the Mast Leisure Park, which is just a very short walk (about 2 minutes?) from
Canada Water underground station. (It's about 7 or 8 minutes walk from Surrey Quays underground station). That's based on the restaurant locator here
http://www.frankieandbennys.com/
together with consulting a London A-Z.
Googling the Mast Leisure Park suggests that it has the usual facilities that similar developments have. (i.e. several bars and restaurants, ten pin bowling, bingo, etc).
Shopping in the area seems to be concentrated on the small Surrey Quays shopping centre, with a boring and predictable range of High Street names (e.g. Boots, Woolworths, etc):

So it looks like the area has reasonable facilities for locals but there doesn't appear to be anything to go out of your way for.
