There's a special offer this Thurs- if you quote 'netmums' before you pay its only £3 for 1 adult and 1 kid under 4, or £6 for a party of 4 (at least 1 must be adult)!
As its usually £8.75 for ds (3) and £2 for me it looks well worth going along!
Any London mums want to meet up there, and form our own mumsnet contingent?
