Sorry nobody responded earlier. I personally haven't been to confession in the Byzantine Rites yet, but I do know what Wikipedia tells me.
Confession does not take place in a confessional, but normally in the main part of the church itself, usually before an analogion (lectern) set up near the iconostasion. On the analogion is placed a Gospel Book and a blessing cross. The confession often takes place before an icon of Jesus Christ. Orthodox understand that the confession is not made to the priest, but to Christ, and the priest stands only as witness and guide. Before confessing, the penitent venerates the Gospel Book and cross, and places the thumb and first two fingers of his right hand on the feet of Christ as he is depicted on the cross. The confessor will often read an admonition warning the penitent to make a full confession, holding nothing back.
