For a person who rarely eats donuts I've had a Lamar Donut, a Bosa Donut and a Dunkin Donut all this month. I bought a dozen, assorted frosted donuts for my co-workers last weekend. I ordered a apple fritter for myself. I can't comment on the other donuts because I didn't try one.
Now on to my apple fritter. What Bosa and Lamar's apple fritter have in common is the lack of apple. It's a good fritter, but I wouldn't call it an apple fritter. Also, Lamar's fritter is giant in size compared to it's competitors. If I'm craving a fritter and i'm in the area I'll stop in otherwise, I won't go out of my way.
