I stand by the register, looking outward, gazing upon a rat terrier attacking locals as they stroll by the front of the shop. The only thing sweeter than the sight of a 30lb dog making a man spill coffee on himself is the delicious donut in my left hand and the honey cinnamon latte in my right. Easily a 9.1

I have no idea why this place is rated so high, we went on Sunday morning and the donuts were extremely dry and tasted old. The coffee was some of the worst I’ve ever tasted. Skip!

Best place to eat in Sag Harbor including all the restaurants. You can get full on these. Their $5 donut is more satisfying thank $50 lobster roll

The donuts were very good and the oat milk cappuccino was one of the best I had ever had—despite my disappointment that they did not have regular lactose-free milk. It was a nice surprise.

Great place to stop by if you are walking around Sag Harbor to grab a coffee or even their delicious donuts. The huge flavor selection fro donuts and other items is amazing. I would definitely recommend coming here. It would be nice if i got a napkin though as the frosting got on my hand.

The mini donut is a regular donut and the regular donut should be illegal. They are gigantic and taste incredible. Worth the money. Jelly donut was a bit eh since it was not raspberry but every other donut was a smash hit.

Doughnuts great. Service lousy as always. Employees act as if they know the owner isn’t present and have no sense of urgency. No air conditioning so don’t know how they pass inspection.

Extremely tasty jelly donut

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.

Skip this place. Went in to order a coffee and got looked over as I was waiting in line multiple times, with no apology. Not busy, only 2-3 people in line. Also, terrible coffee.
