Hilltop Inn BnB and the adjoining Burns Pub and Restaurant provide good accommodation and fresh British fare to travelers at the Rocky Mountain Metropolitan Airport BJC in Broomfield, Colorado. Near Denver, it's a good lunch place, especially if you fly in or out in a small aircraft.
Kids will love an outing to Cypress Point Park on Tampa Bay Florida. It's right in the approach path to Tampa International Airport and the planes fly quite low and directly over this park. It's a great picnic venue with built-in entertainment, plus it's on the water in a fairly quiet area (if you don't count the jet engine noise).
