Sounds like a much more sociable way to spend time then simply drinking, which kids will do anyway, or staying at home playing computer games.

And most parents would feel much better about their kids having a casino night in their home than getting up to mischief on the streets or in clubs and bars.

On the whole I think it's kinda sweet! It's like a younger generation of little Brits playing poker and blackjack while their parents play bridge and 500.
