Any dim sum in... Sao Paulo???
Yes, it is an odd request. But in a city of 11 million people you'd think that it might exist. Well hounds, does it? Thanks.
Well, I heard about Ping Pong but I don't trust a british restaurant chain serving chinese food in Brazil, it just sounds too weird to me. But there is a very nice restaurant called Rong He with a menu based on Chinese fresh noodles (hand made in front of the customers) and Dim Sum . http://www.ronghe.com.br/ . If you're still around you may wanna check that out.
