Food that looks good doesn't always taste good.

Like brain sandwiches.

It doesn't look that good at all

No, that one doesn't. But at least it's cooked.

This doesn't look too nice. It's a century egg

both of those look absolutely disgusting so they must taste great!

this must taste good, by the same rationale.

where is that restaurant?

China, I would guess. I just saw something similar on tv. they also do the same with snakes, so they still wriggle in the bowl when served.

That's quite awful. I prefer the mineral version.
