Go for the Noodles and Pie
It is said that Japanese Business men on Ohau have been known to take a flight at lunchtime to Kauai just to go to Hamurin for a bowl of noodles and a slice of pie.
I would land, jump in a cab, and get some noodles and pie.
You wont be sorry...if you have time...stop at Marriott on your way back to the airport and walk on the beach.
