Recommendations for a 5th birthday venue in N London

[janx]

DD birthday is in September - for the last 4 years we have always had it outside - highgate woods last year...but it is such a rainy summer I am thinking we might need to find an indoor venue as our flat really isn't big enough. Anyone hired something - was thinking of coram fields as it has the option of the outdoor space if the weather does turn out to be nice..any other bright ideas - nothing toooo pricey - tia
