Underneath all of that sits a second visitor with nothing in common with the first. Someone arranging a rehearsal dinner, a retirement party for forty or a catered office lunch is at a desk, weeks ahead, with three or four venues open in tabs, and one of those inquiries is worth a Saturday service. They need capacity, whether a private room can be closed off, whether the whole place can be bought out, what happens about dietary requirements at that scale. One site has to serve them and the person standing on the sidewalk, and almost every restaurant site is built as though only the sidewalk exists.
