Interesting capture and plate design Lou Ann, it is the Fornasetti design of the opera singer Lina Cavalieri, by Piero Fornasetti's, suspect they had lots of different designs in the restaurant :)
@grammyn the tables were made of a material that mimics rough slate, I’m putting a photo on today that will show them better. The surface caught the light perfectly in this shot. Thank you for your wonderful comment!
Is the table flat or does it have the texture that it looks like it has?
