never mind the food, what about the basic hygiene? local street food vendors park their carts in a grotty soi near my place. not only is the soi dirty and full of rubbish, but i have seen, cats, dogs, rats, insects crawling all over the carts. i have never, ever, seen a vendor cleaning their cart either when knocking off work or preparing to start cooking food. i wouldn't go anywhere near food prepared and cooked in these conditions.
