São Paulo is known to be the biggest metropolis in South America and it has even been ellected as one of the uglyiest city in the world. I personally think that people who say that didn't get to know the city very well.
Besides the big buildings (which also have its beauty) and avenues, São Paulo has some colorful spots, such as Ibirapuera Park - that I talked about in this post. Beco do Batman is another place like that. It is not natural, but it is a very nice place to visit to escape the metropolitan life.
A hole street filled with grafitti walls and art galleries in the middle of one of the most bohemian neighbourhoods in the city: Vila Madalena. That's what Beco do Batman is about - colours and art!
What to do
Take your time taking pictures, walking around and visiting the little art galleries there - you can find nice souvenirs to buy such as urban art paintings, cool clothes or even scuptures.
What to eat
Also, if you're hungry, there are many restaurants and pubs around that serve feijoada, typical brazilian dish, on saturdays during lunch. And you can have caipirinhas any time of the day.
