When I first went to the Divine Liturgy at St. George Maronite Catholic Church here in San Antonio, TX, Subdeacon Raymond Casillas was apparently able to tell that I was a Latin (maybe I genuflected or something or other). So, he came over to me, greeted me, then he started talking a bit about the Christian East. Now, I did some research beforehand, I even did my high school senior English research report on the break between the East and West. I’ve also been to a Greek Orthodox DL long long ago my frosh year in college. I would love to go back to a Byz DL, though the Maronite one is pretty cool, too.
Now, some differences: I can’t speak for the Byzantines, but in the Maronite Church, Holy Communion is received by dipping the sacred Host into the Blood of our Lord----as the Master of Ceremonies (my term, for lack of the precise terminology, for the layman who takes the place of roles specified for the deacon in the rubrics) at St. George is sure to emphasize, NEVER on the hand.
Also, we bow when we enter the pew. There are kneelers, but they are never used during the DL itself. The priest incenses a few times during the DL—you can still smell the incense even when it is not actively incensed, but usually it does not cause anyone problems. (I have heard of some churches which use a nasally obnoxious type.) But I don’t think anyone is going to object if you have to leave for a minute or so if the incense starts to get to you. The priests at St. George also chanted (relatively in tune

) the Anaphora in Aramaic. After having chanted this, with a few replies from the people, the priests then ask that the Holy Spirit come upon the Gifts to make then the Body and Blood of our Lord.
Now, as for the Byzantines, as I remember, they use a spoon to dip the Body of our Lord into the precious Blood.
