Don't miss Lappert's ice cream.
I wish I had checked out Lappert's ice cream earlier. It is delicious. If you even remotely enjoy ice cream, I highly recommend having some Lappert's ice cream. I especially enjoyed the flavors which had coconut, macadamia nut and caramel in them (and usually I don't particularly enjoy coconut). Also, the Lappert's store in Koloa has more merchandise you can buy, like more t-shirts and mugs. Lappert's also has a location in Hanapepe, and while that location sells t-shirts and mugs, it's much more of a typical ice cream alongside the road.
