On Saturday night, April 9, my wife and I were walking along 20th Street. We had an 8 p.m. reservation at a restaurant only three blocks from our apartment. The streets were bustling with people. It’s a Cardella tradition that I make a dinner reservation every Saturday night. We like to try different restaurants, so our restaurant destination was a new place we’d never been. Usually, we have a driver take us back and forth. But in this case, we decided to walk because of the short distance.
