New Guy Looking for Advice on Life in BA (Buenos Aires)

Hi everyone. I'm an attorney trained in the US relocating from Santiago, Chile to Buenos Aires next week. Very exciting for me.

I just wanted to introduce myself and say that I am looking forward to life in BA and would welcome any advice on anything about BA as I only know the city as a tourist. Any tips on housing, restaurants, galleries, neighborhoods, etc. would be invaluable.

Thanks and I look forward to meeting some of you.
