Grindstone Coffee & Donuts

Best Donut shop on Long Island. They're huge, unique flavors, good textures and good coffee.

Great donuts first and foremost as well as wonderful staff!

Quiet place on a corner in sag harbor, making fresh donuts. There are 7 to 8 flavors of donuts at a time. The shop always has a different flavor each time I go.

Delicious and unique donuts!! I tried strawberry frosted, churro and glazed. yum yum yum! I will definitely stop here again next time I'm in town!!

Great selection of coffee and desserts.

Very small but nice and clean place. The young man at counter was very nice but the Double Espresso that I had was extremely small and Bland as was the Amon Joy donut. No thanks will never go back there again.

Exquisitely unique, delicious doughnuts and perfectly brewed coffee drinks in a clean, creative atmosphere. Try the "Mexican Mocha", a divinely balanced cup of spicy, sweet rocket fuel.

Awesome olde fashion donuts and latte

Great place, cool vintage style! So many whole-milk alternatives, good coffee creations and the donuts are delicious! Absolutely recommend going there!

There doughnuts all taste like fried dough from the fair topped with coatings. If that's your thing you will love these doughnuts. For me it's The first time i ever threw out a doughnut
