congratz on buying a house in Ongar,
Its a great place to live in. There are many young families, so if you are young and planning [or having] to have kids, u wont be short of tiny-tots, they are very much there. Apart from the Chinese restaurant, there is one India planned as well, not sure if this plan is still on. There is curves gym its very small though.
I've heard of Ongar railway station, not sure when it will appear. Thru back roads you can touch the Navar Road quiet easily. Overall its a great place to live.
