Thanks everyone for the tips!
While I an adventurous eater and do love street meat, it is a biz trip and I don’t think I risk an upset stomach on car ride out to the factories.
On the weekend, I might give the stalls a try 
Couchsurfing is a cool idea but we have booked two hotels (PuLi in the week, Waterhouse for the weekend).
If you know anything close to there, let me know
If I return on my own dime, I’ll definitely will consider couchsurfting.
I was also wondering about boutiques and museums/exhibitions for design related things. Fashion, objects, tech.
Also what neighborhoods are good to check out for designers?
Thanks again!
