I've done video calls from the roof of Stavros Foundation Library, but that's weather dependent. Actually, now that I think of it, I've also done at least one video call from the halls of the Stephen A. Schwarzman research branch across the street. Granted, these are not dedicated co-working spaces where you can make any noise you wish, but some calls are possible.
