Wow! You all are sure passionate about your buns.
I was there this weekend and had the multi bun on the chili cheese dog at Cosmic Rays, DH had the burger. To be honest, I didn't even notice until half way through and then only b/c I had read about it here. DH didn't mind and typically he detests my nutty, whole grain Nature's own at home. To be fair, it's a very, very light wheat and it was just as squishy and soft.
