Oyster Cake

This is the first time I've had Oyster Cake, and I think this will be the last of it. Or not. But this first time experience really sucked. I don't know if it should taste that way or what. At first bite, it has a little salty taste, and then few more bites digged--- Blah, it's a bit bitter, and tasted like unfresh, really stinky thing, I don't know how to explain. I don't know how *Americans can eat this dish and still be 'people that eats most number of oysters'.
