I'm excited to be visiting Paris for the first time soon and will have two Shabbatot to take in the Sephardic life. I've searched the group and found references to Temple Buffeaut and the Grand Synagogue of Paris. I'll be staying in the 8th district, about one mile from both of those places. Anything I should know in advance - any security concerns, like do I need to contact them in advance of going for daily or Shabbat services?
