Let's start with foot chicken. This is one of many things you can get in Phnom Penh. Also bigger butt inserts, shown below.
More natural ways to increase your booty is through grilled street squid.
Or river fish with sauce baggies.
Or cockles. I suspect the digestive risks with eating cockles may be higher.
In any case, there was a lot going on in the street.
Which we watched from above, while eating chicken amok.
While watching the sunset.
