Okay so it's not a sandwich, but if you think about it ... (see here)
Anyway this hotdog was fantastic. There is very little in addition to this that I can say. I can't even be sure the meat they use is actually meat. But who cares about that? All that I care about is the taste, which was meaty and salty, and the texture, which was firm yet succulent. I could have been eating panda or seal for all I cared.
