    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.

    Churro & Glazed

    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!

    Being that this was more of a destination trip for some preemo donuts , I had to find out if this was going to go toe to toe with my new standard in donuts ... SideCar ! I haven't travelled enough across the nation to find the ultimate donuts but I have to say, SideCar is the crème de la crème of clean ingredients, presentation, weight and the feeling afterwards. First off this was about an hour and change road-trip with one of my awesome friends and his lovely wife , and nothing but nostalgic moments discussed on our way to SaG Harbor. When we arrived , I just loved the vibe of the area, people were out, weather was amazing and sun was shining. It seems the hype was living up to its name because they ran out of alot of the flavors they had so as you can see in the pic, that's just about what they had left . The powdered jelly donut, the Boston crème and the other sugar donut I forgot what flavor, but man oh man these three with a latte were pretty amazing. The cafe was nice inside , but you just had to eat the donuts outside, and that we did. I have to revisit this spot again but never alone. I need to share this goodness with some other friends and spread the word. Now if grindstone can open another spot out in Nassau County, I'd be a happy camper . Til then , it's gonna be a road trip !

    Just go here. Everyone loves donuts but this place does them right. The filled donuts are probably 3lbs each and are so damn good. The blueberry jelly was fresh and had the seeds in it. The Boston cream was absolutely the best I've had. The s'mores was the downer in this group honestly. But the absolute best donut I've EVER had was the churro. I'm telling you get it and you'll see.

When I let the staff know they had made the wrong juice, I was treated with hostility, accused of being rude for simply clarifying my order, and banned from a store I had loyally supported all week. An older blonde woman - who I've ironically seen be unpleasant with customers all week - was irritated the moment I questioned the order. She snapped at me for inspecting it. When I explained how it red instead of green, she ordered me to taste it, then seemed annoyed when I told her it contained ingredients that weren't in what I had ordered. I tried to explain what I'd ordered and the substitution I'd made, but she and another brunette employee became increasingly hostile. As they all began bickering amongst themselves about what was in each juice on the menu, so I offered to write down my order to help - at which point the older blonde woman told me I was being rude and said to the other employees that she was "ready to fight me." Over kale and chard... at 9:30 a.m.? Her behavior was so disturbing I just walked away and sat down with my husband, mother, and my baby - all of whom had been watching all of this unfold in shock as we waited for the amended order. Then, while we were sitting quietly, she told me I was banned from the store. Both my husband and my mother - dumbfounded asked why clarifying a juice order warranted being banned. Her response? To my husband, she snapped, "What are you, the boyfriend?" and to my mother - who was with our baby - "I'm not speaking to you." And the manager? He didn't ask a single question or review video footage. He simply said he was going to stand by her wishes. The reality is, I'm just passing through. We were genuinely excited to stock up on some of the great products before heading home -- but now I'll just order everything online. And frankly, it's a shame. This kind of unnecessary hostility in customer service is exactly what drives people away from supporting small businesses.

There are way too many vacant stores and closed restaurants! That being said I finally made it to Cluckmans on a beautiful September day about 1PM. There's a beautiful park with picnic tables adjacent to the parking lot that overlooks the harbor. The restaurant was not busy as I walked right up to order. The place is clean and well organized with about 8 tables and a condiment counter with free ketchup, mayo, mustard,ranch and honey mustard. Since it's my first visit I ordered the Traditional Chicken Sandwich and Hand cut fries. Service was quick but the sandwich is way too big for the small bun, there was way too much Thousand Island dressing and it was spilling out all over the wrapper! I took the sandwich apart and wiped away as much of the dressing and ate the chicken and avocado separately! It was actually pretty good! The fries were a very generous sized sack but they obviously had been sitting for a while because they were not crisp, very soggy and oily! I would like to give them another try but I would definitely think about a larger bun and ease up on the dressing! I wish them good luck!
