My parents used to live there and I would visit every break. If you're going to Oahu, look up a shop called Zuke's Magic and Jokes. It's only open on Saturdays, but that's where most of the magicians hang out at before going to the Kahala Mall (they hang out at Kahala almost every Saturday evening from about 5-6PM til close). They usually hang out by the fountain near Jamba Juice and Starbucks. If you go, tell them Sean from Florida sent you.
