Apologies in advance as I couldn't figure out how to send a PM (is there a way?) on this site.
Anyway, vinhotinto, loved your recs for Lisbon so much that I wondered if I might trouble you to provide some favorites for Sao Paulo, since you indicated you spend time in Brazil too. I'm over here now and trying to find the kinds of places you so easily ID'd in Lisbon.
I know this is Spain/Portugal but I couldn't figure out any other way to do this, as you don't seem to post in the Brazil sections.
