The GeePeeCoo I was talking about for SURE was "street food", NOT restaurant food!
Ya walk down the street, see a little old mama moving skewers over a dinky little grill on a pushcart, say "GeePeeCoo Lah-Duh", and fork over something like 40 Yuan, and she takes a skewer of them off the grill ready to go, sprinkles her special hot stuff on it, maybe turns it a couple more times for show on the grill, then hands it over MAYBE with a paper towel. Ya continue walking down the street - munching direct from skewer.
Now THAT'S eating!
Hafta admit never tried ordering it in a restaurant!
Glad it worked out for ya though.
Editted to add: Just reread your note - may have misread "them" to mean restaurant guys rather than collegues willing to walk ya down the street....
