I suggest that the 4 June Coffee Chat be held at Café Violeta Rivadavia 3899, at the Castro-Barros "A" line station. While this place might not meet with the criteria that I mentioned, the place is magnificent and it's surely worth visiting.
Come to think of it, this is a great idea! Two coffee chats, same day, same time, Camel hosting at Starbucks Alto Palermo and Fred Mertz at his recommended venue! I imagine Cruizes will attend with Fred. Great idea, Fred!
