So I did go last night and honestly, I did not care for it at all. I think it was just a culture shock though, not that any part of it was bad or objectionable - just very different.
One of the previous posters was correct, the chanting was quite odd (the fact that they chanted the entire hour). The priest wore all black, including a black headpiece with his back to everyone for a portion of the service. At some points people touched the floor with their hand after crossing themselves and then some parts of the service, everyone laid completely on the floor.
One part of the service they did the kyrie 40 times in a row.
But! The point of going was to expose myself to something I have never experience and it definitely did that.

The people were very friendly but I donāt think Iāll be returning.
They invited me to visit on Sunday so I could see the divine liturgy service but I am hesitant.
Glad you had the chance to experience the Melkite vespers. I suspect that the style of chant - the Arabic and Greek melodies - may have been the most off-putting element. The various (Byzantine) Eastern Catholic churches (Melkite, Ukrainian, Ruthenian, Russian, etcā¦) each have different styles of chant. To the western ear the Melkite chant may just sound rather strange at first, but with more exposure and understanding one can come to appreciate its mysterious beauty.
The simple black robe (called a riassa) and hat the priest wore - thatās just part of the priestās normal vestments for vespers.
Itās not that the priest had his back to the people, but rather that the priest and the people are all facing the Lord and worshiping him together. The bowing, continuous chanting, facing east together, etc⦠this is how Christians have worshiped from the beginning.
The laying down on the floor, i.e. making prostrations, is a practice done typically during Lent, and was probably accompanied by something called the Prayer of St. Ephrem, a prayer of repentance we pray every day during the great fast (the translation may have been different, but this is what we use in my parish):
O Lord and Master of my Life,
Take from me the spirit of sloth, despair, lust of power, and idle talk.
(prostration)
But give rather the spirit of chastity, humility, patience, and love to thy servant.
(prostration)
Yea O Lord and King, grant me to see my own transgressions, and not to judge my brother, for blessed art thou unto the ages of ages.
(prostration)
