I'm a HUGE donut fan and I have the belly to prove it. I've tried Rainbow, Bosa and Golden Donuts since I recently moved here and none of them come anywhere close to how good this place is. I actually drive 45 min each way sometimes on a Saturday morning just because they're that much better than anything else that I've had in the valley.
Lemon Bismark was phenomenal! Best lemon-fill I've ever had in my life! It's huge and fresh and the powdered sugar is layered on well too. Cinnamon twist was also the best I've ever had. You could taste fresh cinnamon in the bread and the glaze was perfect. The cake donuts are big and they put lots of frosting on them. I could go on and on but you get the idea. Make the drive out to Lamars if you like donuts. If you think Krispy Kreme is a good donut then you're beyond help anyways.
NOTE TO ARTEMIS-People go to Yelp to hear people's reviews on food that they actually taste. If you want to give your opinion on the dangers of hydrogenated oils then go take a nutrition class and write a book report so everyone can be wowed by your knowledge. I go here to find good food, not get a lecture about what I "should" be eating. One star for a food you never even tried? What a joke.
