Great great place in Sag Harbor. During the summertime I always find the time to get here and enjoy these delicious donuts with a cappuccino or ice latte. I love all donuts here, tried almost everything so far but the most fav is the cinnamon sugar one. It’s simple, not too sweet, fluffy, fresh and you can taste it’s a real homemade big donut. The strawberry jelly donuts are also SO SO delicious - it has a lot of jelly inside. Seasonally, they have the blueberry jelly which is also a big yes for me. Their coffees are also delicious and fresh!! Can’t wait to be back here and try other flavors 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!

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.

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

★★★★☆ 4.0 Nick Jacobson · Aug 2023

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.
