Note: Sweet 15 (Quince años) is the Latin equivalent to our Sweet 16
Apparently, this is a new establishment. Their site (Click Here) is still under construction.
It seems to be built like a mosque. I do not know if they are merely mimicking a Mid-Eastern style, or this reflects the personal beliefs of the owners.
But notice the name: Palestino-Libanés (Lebanese Palestinian)
There is a Lebanese aspect to this. Most Lebanese in Mexico are (Maronite) Catholic. However, those Catholics would be more assimilated and Western.
So I cannot say if the owner(s) is/are Muslim Christian; but two Arab ethnicities are involved, Whether by two owners, two styles of food, or one person of two ancestries, I do not know.
What I can say is that is it looks like a classy joint. Arabs tend to have a high station in Latin America. This may be one example.
I suspect this wedding is Muslim. The poster has another video about women wearing hijabs.
Almost all Arabs in Venezuela are Christian, so if these are Muslim, they are probably newer arrivals, which might explain why the music is in Arabic, instead of Spanish.
That being said: This looks like a reasonably assimilated group, here. I do not see women in burqas. Do you?
