"Babi" and other baozi (steamed bun) shops

In the morning if you walk down streets with food vendors/breakfast shops, you might see people crowding around big bamboo steamers full of white buns.  These buns, or "bao zi" are stuffed with meat, veggies, or sweat bean paste.  Another variation is called "mantou," which has no stuffing in it, but may have sesame or chopped scalions sprinkled on them.  Each costs only $.40-.85RMB, and I always thought that if I ever run out of money, I can still afford these baozi...   A soy milk drink complements it well.  "Babi" is a quite popular chain around Shanghai, and they have a slogan "have you Babied today?'  Good baozi should be soft and full of stuffing.  Eat them while hot!
