Judging by the information in other reviews, I'm assuming that this is related to the Paulista museum as I couldn't see any other museum when there.
This museum is currently closed for renovations, but the whole area is stunning and worth visiting even without the museum.
We've been to Paellas Pepe several times, all I can say is that this restaurant became bigger and more professional (there is a hostess and several waiters now) compared to the beginning. The happiest part is that their paella is still delicious and has not changed a bit since. Service is very good and corteous, simply ask for one more...
This charming ice cream shops sells by the weight. So you can choose as many flavors as you'd like. And trust there are more than enough. It's very delicious and great. Threat yourself to many interesting flavors.
Having lunch at Grão Ipiranga is hard for those undecided. The options are in great numbers and tastes. Do watch out for card mismatches when asking for drink or coffee.
Their pizza, esfiha and cakes are also very good. Try a piece of the bem-casado cake, if you have a sweet tooth.
If you want to taste good Brazilian food for an affordable price, you should check this restaurant. They have couple locations in São Paulo. Most of them in locations that are not in the gastronomic route, but you won't be disappointed.
Try the magic chicken without bones with vinaigrette(type of salad mix of onions, tomatoes).
Beware of long cues, so...
