If you're hungry for a deliciously carb-heavy Hawaiian plate lunch, why not go to Rainbow Drive-in and enjoy a meal fit for a president? It's true: President Obama ate there as a kid and tries to make it back during his visits. Starting at 7 am, you can order up a big plate of mahi-mahi, eggs, and rice (or the omnipresent Spam). Lunch specials include loco moco, BBQ ahi, fried chicken, and chili dogs, with plenty of gravy poured over everything. Best of all, nothing on the menu is over $9, making this a rare bargain on a very expensive island. Stop at their shop next door for seasonings and souvenirs on your way out.
