Mooca is a middle class Italian borough, just southeast from "CENTRO" Downtown. The taxi fare might set you back $25-30, it may take you 15-20 min, depending on traffic jam, Sat & Sun are way better though. The Mooca borrough doesn't have as much night clubs as you might think, it use to be a industrial borrough now mainly residential.
When i go to SP or any other city I stay in FLATS, it's just like a hotels , however you have a lot more freedom to bring people up to your room (if you know what I mean), on conventional hotels they will charge you everytime a girl comes up. Try the borroughs closest to the Paulista Ave., such as Jardins, Pacaembu', Moema, Morumbi.

Despite some speculation on the matter by Dr. H, as pointed out, the expansion itself is not thought to be the cause of the arrow, per se. The real questions then are how the Big Bang got started in the first place and why was its initial entropy low. These questions are still open.

The masonry buildings are more fireproof, and easier to meet commercial building codes.
