Definitely visit Akamai Drive-Thru Coffee Stand when you're in Maui. Great coffee in a great location!
Check out this review from the Maui Time web site. It seems they're highly rated on the island. I quite fancy a nice cup of coffee at this very minute, and of course a healthy portion of macadamia nut cream pie to go with it would be heavenly!
