I haven't even entered an Orthodox church. I would love to though, the closest one to me is somewhere in or around London and would take hours to get there. But one day I must do it. It would be an experience to see how the mass goes and communion.
Welcome, Cain.
I am sure that you would be somewhat familiar with the Divine Liturgy as it has the same format: Liturgy of the Catechumens followed by the Creed, Anaphora, and Holy Communion.
Have you ever been to an Eastern Catholic Church? I attended a Melkite Catholic Church for 3 years before going further East. I loved the Melkites as they did a great job in introducing me to the Holy Orthodox Church.
I've only ever been to the following church, highly reformed methodist, baptist, Traditional methodist, pentecostal, Roman Catholic, Church of England (Anglican) and even LDS.
