The ice cream (especially the Kona Joy and Caramel Macedamia Nut) is delicious and the employees are always friendly and helpful. We visited Kope Lani multiple times while in Kona.
Hula Mocha Freeze is second to none. Italian sodas are great with an ono deli sandwich (tortabread is good). My regular is a 20 oz double hazelnuticed latte. Try the amazing volcanoice cream.
