I too am Roman Catholic, we have a Chaldean parish near us, and I have taken the kids there a few times.
As noted above, the Eucharist is the same form that is found in Catholic Churches. There isn’t much in the way of Communion in the hand, so don’t presume that.
The 'Sign of Peace" is also somewhat different.It is not the handshake with the people around you that is common in most Roman Catholic parishes.
It is given by opening up the hand and ‘sliding’ your fingers along with the person’s next to you. It is kind of like offering a hand shake to the person, but sliding the fingers instead of grasping the hand.
It is also given in a particular order.
The priest will offer the sign to the deacon, the deacon will give that to the altarboys, and the altar boys will offer the sign to the first person in each row. They then pass it along the pew.
While the liturgy might be in English (and it might also be in Arabic or Aramaic), the Eucharistic prayer is said in Aramaic. That is one of the reasons I go, so the kids can hear the language that Christ spoke.
Have fun, it’s a very worthwhile experience.
