Manae Goods & Grindz
The best place to grab a snack or picnic supplies is this store, 16 miles east of Kaunakakai. It's the only place on the east end where you can find essentials such as ice and bread, and not-so-essentials such as seafood plate lunches, bentos, burgers, shakes, and refreshing smoothies. It can get hopping at lunch; call ahead to place an order if you can.
