A couple of weeks ago, the Iris Book Cafe opened quietly on Main St. in Over-the-Rhine, and the positive word-of-mouth is already spreading. Owner Julie Fay, who also owns Urban Eden up the street, has transformed this storefront into a sleek, sophisticated space with a very open feel. The muted tones of the interior lend themselves perfectly to the black-and-white photography exhibit lining the walls and contrast well with the eclectic used book selection, with its ratty, multi-hued spines.
