Also, if it is easier for everyone, bubbly has set up a yahoo group for Oct-Dec mommies and there is a nice little calendar function for this and future get-togethers. I think you just need to PM her your email and she'll send you an invite to the group!
Where in Central are you thinking about?? I quite like that "Pizza Express" place just off the escalator - it's on the same street as the Dymocks... is it Lyndhurst? I can't remember rightly... I've only been there once but it was quite nice!!
