RATHER, They can leave the house if you don't mind packing your friend, his wife, the four kids in your car and head off to McDonald's.
We did that over the holidays, but they have money (lots) so we
packed up the Uber (4 kids, three grown-ups who enjoy a Martini or two) and passed on McDonald's and had a great dinner at Flemming's Steak House where even the 6&7 year olds knew how to order from the grown ups' menu.
