An attorney for Christie's Toy Box said Friday that Oklahoma City's ordinance restricting locations of shops selling sex toys and related products is unconstitutional.

The city upped the pressure on sex shops last week, notifying the Christie's chain that its store at 3126 N May Ave. was in violation of the ordinance.

The notice gives Christie's until Sunday to come into compliance.

The city previously issued a "notice of violation" to Adam & Eve, an upscale shop that opened last November at NW 70 Street and May Avenue.
