Delicious donuts with a wide choice of fillings. Definitely a place to go. Donuts aren't as heavy and as sweet as in other places. Recommended to buy a few and share if you want to taste the choices. I loved a banana and a lemon and poppy seed ones. Perfect flavour!

Coffee and donuts in Saag Harbor. Need a quick pick me up? Craving a sweet snack and a cup of joe? Look no further. This cool funny spot has good service and lots of tasty options. If you're in town, stop by. I did not try the breakfast sandwich (as I'd already had breakfast) but they looked amazing. Great art on the wall too.

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

Perfect spot to grab a donut and coffee to walk around sag harbor. Their donuts are on the larger side (not complaining). They’re unbelievable when fresh and delicious if boxed and eaten at home. Also home to some great coffee My go-to is their glazed (slightly citrusy?) or lemon poppy and an iced americano.

Staff were friendly. Went in the afternoon on a Friday and they still had a full selection. $5 a donut is probably acceptable for the location. The strawberry glazed had a deliciously-lemony tang to it. But it was strong enough that I would honestly call it a Strawberry Lemon donut to not surprise you. Jelly donut was very well stuffed; prepare for that. A short step up from Dunkin’ in aesthetics and flavor.

Not bad! The cinnamon sugar donut is really good. The chocolate glazed donut tastes like a cake. But i was not a fan of the lemon coconut at all, it Tastes weird. $5 ish per dodo

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.

Out of the few times im back in sag and stop here, the donuts were never really that fresh. Always look better on the eyes than they taste. Super expensive too.

Never been there, but heard so much about it. Went at about 2pm, they close at 3. Place has a cool coffee place vibe. Something about the girl at the register read attitude to me, but whatevs. I ordered a mini glaze and a hot apple cider. Prices were stupid high. I paid $10 for just that. The cider hit the spot, comforting and warm. The donut, which they are apparently known for was not good. It was so dry. I took one bite and threw it out. Not sure I’ll be back. Sorry!

As a Sag Harbor resident, it has been a fun ride with Grindstone, but that seems to be coming to an end. The stores popularity makes it a off season /mid week only treat, however that isn't the issue. The issue is the quality of the product. Even at $5 a donut, something has changed with the quality of the donut. The whole family (ok, the two kids and dad..) tasted it immediately. Did Sysco cause a change in suppliers,? Who knows, but it's definitely different, and not for the better.

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.
