I REALLY hope they don't walk away. I did the dagwood challenge on December 1st, 2011 (showed my coworkers the picture today) and finished with about 45 seconds to spare. Puked in my mouth twice during it and ate my own puke, then puked in the parking lot after I got my picture taken. Ah, the memories.
Me and a couple buddies were just talking about going there Saturday for lunch. Went to Los Guachos instead.
