In Beijing in the early eighties with a group of backpackers, menu was only in Chinese script, others went to tables and pointed out things they wanted, I thought I'd be a clever dick and pointed to something on the menu. Waiter nodded, of course when it came out it was chicken's feet, considered a delicacy by some, not me though. Paid for it of course and ordered another dish.
Sardinia recently there were stalls selling cavallo on a roll. Just meat I thought, paid got it, took a smell and couldn't eat it. It was of course horse meat. Seagulls had a meal!
China again in the eighties, we were in the very south of Yunnan, Xishuangbannanot not much choice for food so I ordered something from a stall, it tasted ok, turned out to be dog.
My partner at the time was a vegetarian, physically couldn't eat meat nor too much protien or she would be violently ill, she had a tough time in a lot of places, in China she seemed to survive on cabbage fried in duck fat. She did well in India, Nepal and Sri Lanka though!
Now I don't do 'street food' too many occurrences of food poisoning for my liking. Admittedly this can happen anywhere in any kitchen, but of course YMMV.
