food/hotel Sao Paulo
I stayed in the Jardins area when I visited São Paulo.
You have to visit the restaurant, 'Figueira Rubaiyat' (http://travel.nytimes.com/travel/guid...). This is a huge restaurant located mostly under a massive fig tree.
D.O.M. was, well, not really special - I don't see why it belongs in the supposed list of the world's top fifty restaurants. It was really boring...
Also, you have to check-out the shop, Daslu (http://travel.nytimes.com/travel/guid...), a massive mall for the super wealthy of Brazil. Their rosé wine bar, or, their Champagne bar, are quite fun to frequent, yet, this place is really over-the-top.
The Jardins are the best area for a tourist to stay. Especially if you can stay close to the Oscar Freire area where you can find beautiful shops and good restaurants, it's a great strolling area. But Sao Paulo is not a walking city so you are going to be taking cabs everywhere.
I respectfully disagree with the post below about D.O.M. I liked my dinner there very much, but it is quite expensive. If you want to go for a splurge I would choose Fasano, it's better than D.O.M.
Sao Paulo has wonderful food, you can't go wrong. I don't know either La Mar or Dalva. But you can find good Sao Paulo suggestions if you search this board.
