Although I am not a huge donut eater, this is my spot whenever I grab some. Everyone here is so friendly and the donuts fresh/crisp. Try the cronut! They have a few tables indoors where I will sometimes enjoy a coffee and chat. Great neighborhood spot
Jul 20 · Val TFor the past 20 years, we’ve been buying donuts by the dozen for friends and family. Recently, we were surprised to find out that the previous owner Tom had sold the shop; he was much beloved in the community. The new owners are a husband-wife team with years of experience in the donuts/pastries industry. They seem to be wonderful folks working on overdrive to create these delicious gourmet-style donuts. Their donuts are on par with high-end pastries.
Apr 28 · Coral Reef CompanyI got a blueberry old-fashioned donut and passionfruit lemonade, and it was delicious! There's also a nice table to chill at inside the restaurant :)
Aug 13 · Bolt OnGreat local Doughnuts. I always get at least a dozen every couple of weeks. The whole family enjoys. The store owners are super friendly. Every time that I go here the doughnuts are fresh and a plentiful. I like the convince of its location. I have only purchased doughnuts so far, but they offer items on the menu that I must try.
