I don't know the Northcote Rd, so location-wise I can't comment.
Some good friends of mine own a play cafe in Twickenham. They do lots of arts and crafts, build a bear, ceramics painting, ect, and also have a playroom full of toys, a few tables and lots of mags. They do sandwich boxes for the children and toasties for the adults. This is because they don't have 'cooking facilities'.
They have music and craft classes on most mornings.
Unfortunately, they don't make any money out of the cafe. The business rates are stingingly high, they had a disastrous electricity bill last week.
What they do make their money on is parties. They don't pay anyone, it's all done between the two of them. Feel free to contact them to ask any questions, they are lovely people.

Midwifemummy - how negative do you want to be? Here's the thing: if you don't want to visit, then don't visit. Your comments came across as mean (I don't know if you meant to be or not) and its not fair to assume that everyone in The Northcote Rd area will have the same opinions as you! Most Mummy's that I know would WELCOME something like this!
