Shabbos in Havana:
In case anyone needs info regarding spending Shabbos here...
Mincha and Maariv Friday night at Adath Israel was at 15 minutes before Shekiah. The synagogue is officially orthodox, but the Rabbi and myself were the only ones not carrying a cellphone Fridat Night. When I asked him about it later, he said that he and his wife are the only shomer shabbos people left and the community pretty much assimilated after the Revolution.
The Rabbi, Rabbi Yacob Hernandez, also functions as the mohel, shochet, chazzan, and chevra kaddisha.
After Maariv, there was a community wide meal. The meal consisted of wine for kiddush, two challos split among the whole kehilla, and pasta with tomato sauce.
Shabbos morning, shachris was at 7:30. That was again followed by a meal of pasta with tomato sauce.
Mincha and shabbos (no minyan) was at 45 minutes before shekiah, followed by a third meal of pasta and tomato sauce.
(If you havent figured it out, the community is super poor; Im not sure if there will be a sudden influx of Orthodox visitors for shabbos now that there are flights, but they definitely dont have the infrastructure for that).
All in all, the experience was surreal and I strongly recommend everyone visit before theres a McDonalds on every block.
