I was eating at a Vietnamese restaurant with some Vietnamese/Americans who ordered some kind of fried shrimp. They were gigantic and fried with some kind of salt glaze fried on. Allegedly, the frying process converts the shells into "eddible" crunchy stuff. Great fun was had by all watching bubba peel his giant shrimps. he he he. giant shrimp. They were very large for shrimp.
They also talked about another deal, a "Sea cucumber" which you should ask about before you eat it. Sounds innocent enough right? Nope. Not going to eat it.
