My worst experience was steamed octopus in Hong Kong. It was brought to the table in a lidded bamboo box. When the woman took the lid off, the tentacles began to
ooze out of the box. It was still alive, though somewhat steamed.

When they saw the hues of green we were turning, they offered us jellied pigeon instead.
