    Amazing donuts. Friendly service. Cozy Sag Harbor cool vibe. Highly recommend the passionfruit coconut doughnut with coffee of choice! I like it with ice mocha. Montauk Ice Tea also available and endorsed by yours truly.

    I was shocked to walk up to this location and find a line out the door. While we had a decent wait, the food and service made up for it! The location itself is also very cute (I was in love with the VHS tv they had in the back playing old movies!) My iced coffee was wonderful and the donut was delicious. The barista staff were quick and very helpful. Definitely a pricey location (about $5 for a donut) but I would go again!

    3.5 stars 4% credit card fee They may not be the best donuts I've had but I keep going back! Flavors don't seem to change too much. I had a strawberry jelly donut recently. The next day they had blueberry jelly instead. My favorite is what I've gotten in the past, passion fruit coconut (I think). I do enjoy their specialty coffee drinks, even if they these past two times they've been lacking in flavor. I had the cardamom mocha, which I think is new. Unfortunately there wasn't much cardamom flavor. Next I tried the maple latte. Two coffees and 2-3 donuts cost about $24.

    Great coffee. Great service. Incredible donuts! I don't really like donuts but my kids wanted some. These were delicious. Lite fluffy. Really really good!

    Grindstone Donuts in Sag Harbor, NY. Saturdays are for donuts in Sag Harbor, NY. @grindstonedonuts serves their brioche and cake donuts year round (#grindstonenevercloses) with their homemade glazed and fillings. Grab a cup of their single-origin organic coffee to pair perfectly with your donut. Nutella S'mores Donut Boston Cream Donut Insta: @thehungrysw

    Stopped by for a cappuccino, which was smooth and delicious. The donuts looked fantastic, but unfortunately, they were a bit of a letdown--dry and flaky. It's a small spot, definitely more of a grab-and-go atmosphere. The service was friendly though, which added to the overall experience.

    I'm more a cake donut fan, but having tried a few of these, I can definitely say these are the best yeast donuts I've had in a long, long time. There's quite a variety of flavors. The staff are all nice as well. They can run out quickly, depending on how many they've made for the day and the demand. It was our third time stopping by there, but the first where we were actually able to get donuts. It's a testament to the quality of the donuts for sure.

    Coffee is good but the doughnuts are outstanding. Grew up in PA Dutch Country (feels like the doughnut capital). Unfortunately, they're no longer made with any integrity- loaded with cheap & artificial ingredients. Had the Churro & Glazed. Possibly the lightest, cleanest, tasting doughnut to ever grace my lips. That isn't always a good thing, but in this case it was. Flavors & filings sang in the absence of the waxy aftertaste of heavy palm oil & cloyingly sweet artificial flavors. At $50-$60/dozen (don't care Hamptons still ridiculous) you won't enjoy more than a taste & a lot of pressure to make the right selection. This coupled with the awkward space with no seating & visibility of what's to order blocked by lines, means there's room for improvement before charging $5 a doughnut.

    What a line! Is it worth it? I'd say yes if you have the time and stamina to find a parking spot. Located on the main road in Sag Harbor, its a popular spot for a quick coffee and quick donut as a snack. The donuts run quick, theyre also okay and not mind blowing. The coffees are totally worth it thought - they also spice them up different ways. Overall 8/10

    After a few visits and trying a variety of donuts I'm upgrading to 5 stars and my favorite donut shop on the East End. Today we tried maple sea salt, strawberry jelly, nutella smores and a mini strawberry sprinkle frosted and all were excellent. The strawberry flavors actually tasted like strawberry. The full size donuts are enormous. You can easily share one. There are a few 'mini' sized donuts which I'd call 'normal' size though my 2 year old put away a mini with ease. Credit cards accepted.

    The maple donut was the most flavorful donut I think I've ever had. It was so light & fluffy! The coconut passion fruit also was delicious! I had the peanut butter mocha iced coffee which was good but not the best. By far the star of the show here are the donuts.

    As a former donut shop owner I find it very satisfying to try as many donuts as possible wherever I go. If I had more stomach left, I would have eaten at least 2-3 more then the chocolate sea salt version in the picture. The donut itself was light and airy with the typical yeast raised base. The frosting was a chocolate base with a dose of sea salt sprinkled atop. Being the Hampton's, I certainly did not expect the prices to be reasonable so the $4 price was totally okay in my book. I was hoping to get a bit more saltiness crunch, but it was later in the day so the salt kinda blended into the background. I was kinda hoping for some Maldon but couldn't recognize yeh crystals by the time I dug in. The shop itself was quaint and staff very nice. Can't wait to get back for a proper dozen!

    Great place for coffee and donuts. The churro vanilla cream donut is our favorite! The seasonal donuts are something we look forward to.
