Grindstone Coffee & Donuts

Donuts are phenomenal and great staff! But they charge u an arm and a leg even just for one donut so going there will be a once in a blue moon stop for me.

I have absolutely no idea what people are talking about when they say these were a disappointment. I've made a point to come to Grindstone everytime I'm out east since they opened. The donuts are the lightest fluffiest donuts I've ever had, whether they're fresh out of the oven (baked in small batches so they're very often fresh) or if I walk in and get one off a sheet that's been there for a bit. The coffee is great too, but this isn't a coffee shop, they serve very high end coffee sure, but their staple is donuts. The coffee's just a bonus. The shop is cool and comfortable with a focus on local art, and a bit of the macabre. Don't miss this place, seriously.

Really good coffee and donuts! Definitely want to go back and try more donut flavors. I had an iced chai latte that was delicious. We walked down to the marina and were able to enjoy it there!

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!

Best coffee & donut spot in Sag Harbor! All staff members are so friendly and provide excellent service whenever I stop in.

My go to order is an iced latte with oat milk, but I've ordered many other drinks off their menu and was never disappointed. While my favorites would be either the Maple Sea Salt or a classic Cinnamon Sugar, you can't go wrong with any of their delectable donuts either!

I'm from Montreal. I was visiting my niece & her husband & 3 kids. This was the 1st place we went to eat. I ordered mini donuts for everyone. They had coffee (not the kids❣) & I ordered the turmeric tea latte. Best tea ever, wish I could get that recipe 😋 Connie

My mother, a baker, was impressed by three things: the height, the dark chocolate in the chocolate glazed, and the lemon poppy seed. So listen to my mother and get the chocolate glazed and the lemon poppy seed.

Grindstone is a great place to start your morning! Started off with a iced beetroot latte, delicious and unique. With that I got the bacon egg and cheese… this sandwich is a must have. High quality delicious take on a BEC sandwich. Overall great spot, and might get a shirt one day. Would recommend to anybody.

Breakfast bacon sandwich had the perfect ratio of bread to egg to bacon. Donuts were all great. Got everything to go and ate at the picnic tables across the street.

The donuts look better than they taste. I only tried the dark chocolate frosted donut. The donut itself was meh...kinda dry and boring. Dark chocolate frosting was decent but thin.
