The Mezzanine

As I said to Elisi, most of the barbecues my daughters attended as teenagers tended to expect folks to bring food - but, then, you have lots of impecunious young people and the parents providing the grill and a few basics.

In England the weather means barbecues are a risky proposition, and most folks throwing a barbecue expect to provide the meat and basic salads, with "frills" and bottles coming via the guests. I suspect that is so a backup plan involving an oven and an indoors room can go into action when (rarely "if") it rains!
