american style trick or treat in London?

[Unanimes]

My children are half american and are accustomed to the tradition of Halloween and trick or treat, for young children.
Do you know where to go, in which streets people would celebrate Trick or treat american style? and Halloween? In London?
Which day? 31st or during the week end?
Is there an american community here, that would celebrate it the same way they do in the US? A place in London where trick or treat would be more celebrated like in the US? Where it is so genuine and fun?
Thank you for your advice

It's Child Central here and there are streets that do the whole shebang -I'm reluctant to name streets because they are already inundated - I pity the people in the street who don't care for Halloween - perhaps they go out or hide on that day.

My grumpiness aside, where I am, people call on houses that have Pumpkins outside, or at least lots of decoration. It seems to work well.

Or when they were younger, we agreed to call round to each other's houses.

Like Gasman, I am also from the Scottish tradition of "guising". However there is a very important difference: no threats are involved. You get dressed up in your costume and call on the neighbours to do a "party piece" - a song, a joke, a wee dance etc etc and they reward you with sweeties. You have to MAKE AN EFFORT and no threats are involved. Also the lanterns are made from turnips (swedes) and smell lovely. Costumes can be any kind of fancy dress, there is no rule about being ghoulish - I fondly remember a geisha outfit fashioned by my Mum from my Dad's silk dressing gown.

None of this helps the OP but I just wanted to explain the differences..

Maybe the OP means "genuine" as in properly dressed up and asking for sweets, rather than money? I have experiences that outside of London

In this bit of London, I've hardly ever experienced anything other than genuine trick-or-treating. Still hate it though, especially when they don't say Thankyou.

That sounds nicer
