The Dandelion Cafe, Chiswick House, Chiswick W4.
Visited this today with a friend after seeing it advertised in a local magazine for families.
It's in the cricket pavilion in the grounds of Chiswick House and has been set up by local Mums (opened at the end of August).
Opening times are 10am - 3pm Mon to Fri.
There are LOADS of toys for babies & young children and it has both an indoor and outdoor play area.
Tea, coffee (cafetieres), light meals (eg pasta & fresh tomato sauce, cheese & ham toasties) plus nice cakes.
Cost: £3 for first child and £1.50 for siblings.
Spent about 3 hours here today - our children had a lovely time playing happily and our toddlers really enjoyed their lunch, as did we!
I'd be happy going on my own too, there were a few mums (and dads) on their own with their little ones.
