Ronald's is AWESOME!!!!
I love their donuts, don't get me wrong, but i went through a phase where all i wanted was a blueberry muffin for breakfast. They ALWAYS had them, along with chocolate and a couple other that really didn't suit my fancy.
To the dounuts, i've probably tried 75% of the different kinds and they're all good. The donut hole special is great too, a dozen for a buck i think it was.
I would give my money to Ronald's donuts any day over the chains like winchells or dunkn donuts.
I could go on forever about the quality of their donuts, but i think you should get your butt down there and have 1, 2 or even 3.
