I recently discovered Greene's on the south side of downtown Decatur. It's on Trinity Place, a street that I hadn't been on until recently. The building it's in appears to be an old bank or post office. It's quite large for a candy store and interesting to look at. I assume that they have party facilities but I didn't ask.
I decided to try a peanut butter cup. It was much more delicate than a Reese's, which has oily and coarse-textured peanut butter. Greene's cup was smooth and blended the peanuts and chocolate very subtly. It does seem to me that chunky peanut butter cups would be a good idea, but I don't recall ever tasting such a thing.
