Days out in London for under 4's when it's wet/cold

[SpareWheel]

I've done a bit of trying to find stuff my 2yo DD can do in/near London when it's wet and/or cold.
Love to hear more ideas, but so far I have found these places, all of which I'd recommend:

BLUE KANGAROO in Fulham - great food for adults and kids and soft play:
www.thebluekangaroo.co.uk/
IT'S A KIDS THING in Earlsfield - standard cafe food, but nice little soft play centre and one for under 2's! You need to book ahead:

SEVENOAKS LEISURE CENTRE - there is a toddler gym between 9.30 and 11.30 on Monday with soft play and tricycles:

The leisure centre is also next to Knole Park & Knole House (www.multimap.com/map/browse.cgi?lat=51.2715&lon=0.1961&scale=10000&icon=x) so you can go for a pleasant stroll around the grounds afterwards!
TREASURE ISLAND SOFT PLAY in Swanley:

GAMBADO in Beckenham: www.gambado.com/beckenham_play.html
HUGO'S play centre in Richmond:

BRENTFORD FOUNTAIN Soft Play area (close to Kew Bridge station):

EDDIE CATZ in Putney:

I know it's a bit heavy on the soft play, but I'm stuck for inspiration. Anyone got any more ideas for nice days out when it's wet?

Discover in Stratford is fantastic!

Science Museum - the Garden in the basement is meant for 3-6 yr old, but lots for a 2 yr old to do, also Pattern Pod at the rear of the ground floor. 3 yr old DS loves the whole museum now. I'd say 2 is a bit too young for Natural History Museum, but it's great for 3 or 4 year olds.

Topsy Turvy World behind Brent Cross shopping centre - really great soft play with lots of extras like dressing up clothes, touch screens and air cannons that fire foam balls.

Childsplay Cafe in Chiswick near the Hogarth Roundabout.

Jumbo's play gym at the Heathrow Gymnastics Club.

The London Butterfly House and the Tropical Rainforest (I think that's what it's now called) in Syon Park. Only there till autumn 2007 though. www.londonbutterflyhouse.com/

The London Aquarium.

Also, Kew Gardens is surprisingly good on a cold day as it's got lots of heated glasshouses full of interesting stuff, and the play area is indoors.

I forgot - we also tried out Brilliant Kids near Kensal Rise station, who were very accommodating for our 2yo DD who made a big messy painting in the playroom next door to the Cafe. The food in the Cafe was very good and all freshly made in front of you by a very busy lady! It turned out to be a bit of hike for us, but DD loved it.

The Museum of Childhood in Bethnal Green is great...went recently with my DD1 (3.8) and DTs (nearly 2) and we all had a fantastic time. museum of childhood

It has a cafe which is quite pricey, but also has an area where you can eat your own picnics.

Just looking at my mug created by DD1 & DD2 has reminded me that All Fired Up on East Dulwich Road in East Dulwich is a really good bit of entertainment and you get the product of your DC's artwork (mug, egg-cup plate etc.):

Kew Gardens has Climbers and Creepers indoors for kids too

and its only 5 min walk from Kew Gardens tube

Bump!
