Meeting 10 mums, 10 babies of 1YO, suggestions??

[sennix]

Hi wise mums,

I am meeting up for lunch for 10 mums and 10 babies (ages between 9 month to 16 month, so crawling and walking) in central London.

They all making an effort to come to London, so it would be really good to have a good place to eat and hang out. Can you think of somewhere, it could be super??

Suggestions so far - Tate modern switch house basement (space, but no food)
Welcome trust (food, but no space)

Any tips would be great!!
