BsAs, I will be back. I arrived after Yom Kippur, stayed for a week, and loved it all, despite the 4 days straight of rain (and the first rain I had in my entire trip).
I spent the days walking around the city, looking at gorgeous architecture from a time when Argentina had incredible wealth, and built their cemeteries to show it. I walked from monuments in plazas to sculpture gardens to parks filled with picnickers.
The Jewish community in BsAs was incredible. On Shabbat, I went to two different shuls and was hosted by local couples who I was introduced to via friends in Israel. Their hospitality was unparalleled, and I found myself having to reject invitations as they poured in. By coincidence, I booked a hostel a block away from the local Chabad, and so I ate there the first night of Sukkot. We sat and sang and carried conversations in some mix of Spanish/English/Hebrew/French. I walked to a beautiful Sefaradi shul on chag morning, which was followed by a community lunch in their enormous sukkah. It was perfect.
Also, there are so many kosher restaurants. I fit in as many as possible – steak, sushi, bagels, pizza, ice cream…. However, I had a hard time finding kosher wine. The South American Jewish community does not seem to be particularly interested in wine, which is a definite stain on their record.
