This is my hometown airport.
Recently they opened the restaurants & shops for one day to people who were not traveling. You still had to pass through security. They should offer this more often. They use a separate security line so it does not impact travelers. We tried the new martini bar which was great. Our favorite shop by far was Bottega Dei Sapori. They were friendly, attentive, offered samples.
It would have been nice if the airport and shops decorated for the holidays. There was only one decorated tree. The live band playing was loud and awful. Next time, turn down the volume and try holiday music or instrumental music. Use recorded music if you can't get good talent.
It's also nice to see there is finally food/beverage options on the land side especially the Starbucks by baggage claim. It's a shame these places aren't open later in the evening. I've not been able to try any of them.
