if you see a long line, that's where you'll know if the food there is good, love street foods but you have to beware of dirty vendors.
remember when i went malaysia some place was selling "chicken bum" yea their asses nicely cooked... it tastes really good
I agree but i like it when they roasted chestnuts in winter time and then shout out in your face you wanna buy some.
I run for the curried fishballs each time I go back to Hong Kong, gotta be careful of the vendors tho, I go to the ones that I knoe I can trust in, cos you do get vendors who sell rubbish items!
