I had a 5 guys one the other day (saw it on the menu for the first time; apparently it's always been there) and it was surprisingly very tasty
The hot dog may even be better than the 5guys burger now(http://www.autoadmit.com/thread.php?thread_id=5604026&forum_id=2\u0026mark_id=5310690",#48147919)
The hot dog was "out" for a while but I have seen places popping back specializing in them lately. I had a good one with a pretzel bun a few months ago(http://www.autoadmit.com/thread.php?thread_id=5604026&forum_id=2\u0026mark_id=5310690",#48147965)
