Lighthouse Landing is out of business at the airport as of May 2013. The new restaurant at the airport location is Arenas. These are the same people who operate Arena's Deli and Bar in Rehoboth, Arena's Cafe Rehoboth, Arena's Cafe Lewes, and Arena's Cafe Longneck in Millsboro.
They have a very good reputation. As Arena's operates in the old Lighthouse Landing location, you can still watch the planes come and go as you eat.
