We just got back from a 2 week trip to the Big Island, staying at an Airbnb with a kitchen in Kawaihae, about 20 minutes north of Waikoloa. The grocery store at the Queens/Kings shops in Waikoloa is okay for salads and sandwiches, but the Foodland in the Mauna Lani shops (the next resort area up from Waikoloa - about a 5-10 minute drive) is better. It has a smaller selection but big, high quality sandwiches at $5.99 - 7.99, fresh cooked rotisserie chickens, and most importantly, fresh, high-quality poke at a very affordable price (roughly $5.99 per half pint container).
Also, it's a closer, easier drive up to Waimea then it is to Kona and there's quite the bustling food scene up there including some decent, relatively bargain options. Big Island Brewing has great beer and good, moderately priced food, better IMHO than Kona Brewing and there's a really good barbecue place up there called The Fish and the Hog.
Anyway, have a great trip! The Big Island is one of our favorite places in this world, so much so that we are looking to temporarily relocate there.
