Hanzawa's is hard to find the first time, but worth the trip. The best landmark is where Kaupakalua Road and West Kuiaha Road intersect. You travel one more block on Kaupakalua, away from Makawao town, and it's on the mauka side. They really have a great selection of produce, including lettuce, tomatoes, corn, arugula, strawberries and more. Their prices are lower than the major chain stores and their produce is better.
