It's really not hard to find a communal gathering spot a little more high-brow than McDonald's
For example, I live in the suburbs of San Francisco. Not far from me there is a delightful and quaint organic bakery, and across from that is a gorgeous park. On weekends after my kids finish lacrosse practice, my wife and I take them there and enjoy some cheap ($9 each) chocolate croissants while they play on their tablets in the park.
People choosing to congregate in a McDonald's is as inconceivable as choosing to meet up in an outhouse or an abbatoir to me.
