It's sometimes asked what to do at HNL during a long layover. If you don't have time to actually leave the airport area but want to get out of the airport environment, there is a small "strip mall" kind of shopping area about 10 minutes away on foot from baggage claim area. They have a Starbucks, Jambo Juice, a couple of restaurants including one that serves typical Hawaiian plate lunch, a convenience store, and other types of services. It's not on the beach and there's nothing much to look at, but might better than trying to kill a few hours wandering around the airport itself.

It's called Airport Trade Center. Located on Paiea Street at the top right part of the airport map posted at the top of this thread.
