Grindstone Coffee & Donuts

Might be the best donut that I have ever had and I consider myself to be an expert.

Don't just get a sweet treat make sure you also pick up one of their delicious coffees.

Good coffee and made a proper flat white (which is rare in the USA. Don't @ me, because it's true). A tad on the expensive side but it's Sag Harbor, so I expected it to be pricier than an average coffee shop.

Yummy donuts! I ordered a dozen! 6 glazed and 6 sugar! Very fresh and delicious!

The best donuts! Great coffee, super unique breakfast sandwiches. Our favorite Saturday morning spot.

Excellent coffee and donuts ! Although they were more "beignet" style than the typical American ones they were delicious and huge !

Omg ! The egg nog donut was off the charts !! I loved it so much I came back later in the day only to be told It was SOLD OUT ! We also really loved all of the specialty coffee drinks such as peanut butter spicy mocha and my kids loved the hot chocolate and sugar and spice donut holes . This place has the best donuts EVER!!! It’s worth the calorie spurge. Just go for it ! ENJOY 🤍

Ordered a flat white. Good flavor (they use Stumptown coffee). Donuts were pretty tasty with lots of flavors to choose from. No seating but right near the water where there are picnic benches.

The lemon poppyseed donut was light and fluffy and delicious! Almost melts in your mouth like cotton candy but not as sweet!

We were very excited to try the donuts and got a dozen to try a bit of everything. It sucks to say it was disappointing. The icing on the donuts was great however the dough itself was bland, even the chocolate one. There was no flavor to the dough that even the icing wasn't enough to carry it through. I was especially excited to try the lemon poppy but other than the icing which was delicious the rest was flat. I was hoping for the flavors to carry our throughout the donuts with poppy and lemon in it. So if your looking for no sugar tasting donuts then great but for the price of each to have just the icing having flavor it was a let down.

Grindstone has the best doughnuts on the Island! Their doughnuts are super fresh and delicious. They have delicious toppings like s’mores, pumpkin spice, churro, and my favorite lemon poppy! Definitely going back for more
