It was a Bar and Restaurant Sadie.
Not a back garden.
It was like a large block 5 communal back garden.
My young next door neighbours are in the process of putting a bar in their back garden. They have a lovely big barbeque, a slide, a play house, sand pit in a table, a man shed is being built soon, they have a fair sized lawn which will (at a guess) soon have goal posts at either end, a basket ball ring, recliners and a small paddle pool in season. Also terraced area.
In the past, I have had 3 neighbours with their own swimming pool, 2 with tennis courts and even one with three lakes in the hillside, with gravity fed large fountain in the middle of the lower one.
It was like a large communal back garden. Just becos it isn't like any gardens that you had in your neighbourhood, doesn't mean that there are not gardens of a generally similar type to 5A tapas area.
And the group of friends were just 50 metres away (crow flies) from 5A patio doors, with the whole patio area illuminated by the street light immediately across the road.
