Don't bother with Clowns nursery in Golders green. Despite reputation, it is pretty dodgy in there. Unfair classes allocation and arrogant /uncaring management. They are just after your money and NOT the welfare of the kids. Pregnant mums ( potential for more business) or those living in the right postcode get best pick. Look elsewhere if you care about your child's well being
