    Naughty List, Purple Haze, Lilikoi, Strawberry fields
    Melisa A.

    Stopped by Holey Grail Donuts in Kapa'a mid-afternoon to grab a sweet treat for the family. We ordered four donuts: the Naughty List, Purple Haze, Lilikoi, and Strawberry Fields, along with a couple of coffees. One thing that really stood out was that the donuts are made to order, which is pretty impressive and definitely adds to the experience. The flavors were creative, and everything tasted fresh. The coffees were good too and paired nicely with the donuts. That said, these aren't your typical donuts. They're smaller than what you might expect and come with a higher price tag. The texture was also different from what I was anticipating. Rather than being light and fluffy, they were denser and chewy. Some people may love that, but it wasn't quite what I was looking for. The truck itself is located in a random parking lot, but there's plenty of parking, and it's easy to stop by. Overall, I can appreciate the quality ingredients and made-to-order concept, but the size, price, and texture didn't quite win me over.

    A friend recommended I come here for donuts. She was raving about how it's one of her favorite memories from Kauai, and I can see why. These donuts are petite and delicious. They have more of a mochi texture than your classic donut, which I enjoyed. They're not too dense. Each donut is $4.50. We ordered 1 strawberry fields (local strawberries, green tea swirl) and 1 purple haze (ube, lilikoi). The flavors were amazing! They even change out the donut flavors seasonally. The staff kindly packaged them in to-go boxes for us when we said we planned to eat the donuts a little later. They also sell cute merch - shirts, hats, mugs, etc.

    Donuts secured!

    Stopped by after a visit to Tamba and were so glad we did! These donuts were hot and fresh and were some of the most delicious donuts I've had. We got a 9 pack so we could try multiple flavors. Our favorite was definitely the lilikoi and the cinnamon crunch coming in at second. I liked the fact that the donuts aren't huge they are the right size to share but are small enough that you can order more than one to try more flavors. Wish we would have had time to get them another day because they were so good.

    Ordered every donut available! Smaller than you'd think ima. Good way so you can get through them all. We had 6 people team up to enjoy these. Favorite was the lilikoi! Normally I worry that's too sweet but this was perfect

    Cute little food truck donut shop. Donuts made fresh to order, can really taste the freshness and quality of ingredients (especially Lilikoi) Lilikoi donut - 8.7/10 Original sin - 8.3/10 Strawberry matcha - 8.2/10

    Incredible! The hot single is perfectly sweet and savory all at the same time! Served hot, fresh and delicious! Do not miss these Taro donuts while in Kauai. There is another location Princeville, as well. Both were phenomenal.

    original sin

    We loved Holey Grail Donuts! The donuts were made fresh right in front of us and you could truly taste the difference. Warm, soft, and so flavorful. The Original Sin is an absolute MUST definitely one of the best donuts we've had in Kauai!

    Tried out Holey Grail Donuts in Kapaʻa and I get why people like it. The donuts have a texture that feels different in a good way. Crisp on the outside and soft on the inside, which really stood out to me. They rotate flavors pretty often and use local Hawaiian ingredients like lilikoi, which keeps things interesting without feeling gimmicky, like adding a random flower on top of a rice plate dish. It's the kind of place where you can try something new or just stick with flavors that sound good or familiar to you. Service was quick, and the food truck setup in the parking lot makes it an easy stop if you're already in the area. Definitely worth checking out if you're on Kauai and want something a little different from the usual donut spots.

    Made to order doughnuts! They came out piping hot with local flavors. The cocoa nibs were not my favorite for a doughnut topping. I would recommend the passionfruit!

    Have seen them on social media for quite a while, but had never gotten to stop in. Finally got to today! We got a 4 pack so we could try a few, and a couple of iced coffees. The donuts- the original sin and the lilikoi are two of the best donuts we've ever had. Perfect balance of flavor- hot, sticky and yummy. If you are from Portland, think of Phipps donuts with Hawaiian flavors. So good. The purple haze and the chocolate crunch were both good too. Its just that the first two were jaw dropping. No complaints on any of them. The coffees were OK. My first couple of sips were better than it seemed after a few minutes. Maybe the ice watered it down quickly? Anyway- this place is so good! If you are in Lihue or Kapaa definitely stop by!

    Made to order donuts, warm and moist. Outdoor seating underneath the little roof, in case rain comes. Hot coffee was a bit sour.

    If there's one thing to say about Holey Grail, is that its aptly named.....these donuts are a religious experience. Made to order with fresh Hawaiian ingredients, these donuts are everything donuts were meant to be. We arrived around 8 in the morning, and found no line and almost no wait for our 6 donuts. While they were all delicious, make sure you try the Lilikoi! One thing to note: these donuts are a quite a bit smaller than your typical Krispy Kreme. (Another reason to try as many as possible!)

    We tried these donuts on our first day in Kauai and then we had them every single day that we were there!!! The textures, the light airy fresh hot donut, the tropical flavors were all a hit with our family! My daughter preferred the classic while we loved the passionfruit, guava and original sin (maple). I highly recommend trying them and also having them daily as calories on vacation don't count! The coffee (macadamia) was also very good! There is limited parking in the food truck compound - they have an app where you get points etc for ordering and you can order ahead. The wait time is usually 5-10 mins as they make each order on demand. The price is also reasonable- with discounts on bulk orders.

There's even a small merch booth to browse while your food is being made. We waited about 20 minutes, but the staff were incredibly friendly, and it was well worth it. I ordered the Lifeguard Bento, which comes with the OG fried Spam musubi, truffle tater tots, choice of poke (I got spicy mayo), and rice for $20. The fried Spam musubi was so good that I'm not sure I can eat musubi any other way now. I also thought the truffle tater tots were an odd choice to offer at first, but they ended up being some of the best tots I've ever had, and the portion was generous. The spicy mayo poke was fresh and flavorful, making the whole plate a pretty solid value. This is one spot I'll definitely be coming back to every time I come back.

Wow literally so good and so worth getting! Staff is friendly and trying to work hard but wow the literal longest wait ever. It's a cute spot to wait in, but we were waiting for like 40 minutes for our food. It's a little hard to find since it looks like it's in a residential area but keep looking until you find this gem!

I considered going back to ask for them, but honestly, I didn't because I was worried the employee would be even ruder than she was when I placed my order. I also tipped 20% because I truly believe in taking care of people who work in the service industry. We also tried the katsu musubi and the fried musubi, and all three dishes were absolutely delicious. We've visited both locations, and while the food was excellent at each, the Poʻipū location lacked the warm, welcoming spirit you'd hope to experience while visiting Kauaʻi. That said, much aloha to Kauaʻi. We had a wonderful trip and can't wait to come back.
