A little while ago I saw an episode of the Food Network's "The Best Thing I Ever Ate" and Duff Goldman talked about eating shrimp heads at a Japanese restaurant. He said they aren't usually on the menu, but if you ask for them you'll get a huge plate of them.
I've never seen anyone eat a huge bowl of shrimp heads at a Japanese restaurant, but if I did, I'd order some. They looked so delicious. Does anyone know if this is true or common? Is it ok to request things off the menu? I'm thinking of going into my favorite Japanese place this weekend and trying it out, but I don't want to be looked at as if I'm a complete freak.
