When you're bored with Chanel, Coach, and Gucci, head over to Spark for items that no one else will offer. You've got to be looking up, or else you'll miss this gem of a store in Waikiki located on the second floor. Popular with Japanese tourists, this is a great place to pick up collectible kitschy products from the ‘70s, ‘80s, etc. It is recommended for those who like unique souvenirs.
