Hilo Hattie carries all kinds of touristy Hawaiian stuff - flowered shirts, souvenirs, and Hawaiian food products like macadamia nuts and locally-grown coffee. Their prices seemed reasonable ($10-$50 for flowered shirts) and you get a free lei made out of shells and free samples of local coffee when you walk in the door. If you're flying into Kaua'i on Hawaiian Airlines you'll automatically get a coupon for a free T-shirt or mug when you spend $25 here.
