Cantonese chow mein - food poisoning. Maybe because it was mid afternoon and this dish involves so many different kinds of meats and they cut a few corners on some if them? Either way, I could tell right away that a few of them weren't fresh, i just didn't know how bad they really were until later. Last weeks BBQ pork slices? Rancid chicken? Check, check. Maybe their other dishes are awesome? I will never know, since I won't ever be returning. This place had a high rating on urbanspoon too.
