What happens to a place when restaurants disappear? There’s something deeper than just the exchange of the food that’s lacking. Small interactions in so-called third spaces that add up to give eaters a sense of identity within their own city. The spaces, rooms, great effort and expense that go into the counters, tables, curtains, wallpaper, plateware — it’s all the great and fragile theater of dining. Restaurants provide an incalculable amount of culture, texture and humanity.
