Children Party Planners in London - Who's the best?

Hi everyone,

I've been looking at hiring a party planner for my boy's 4th birthday coming up in August.

I've been looking at getting in touch with Dazzle & Fizz - www.dazzleandfizz.co.uk/party-services/party-planning - but I was wondering if there were any other bespoke party planners in London, which people have used before?

Thanks

Mandy
