Hammontree's (right behind the Ozark Brewing Company on Dickson) has a blueberry grilled cheese sandwich. I won't review the place cause they don't have fries, but it may be worth a trip there to freak someone out.
You: Hey, I've got a powerful hankerin'(sp?) for a grilled cheese sandwich-but I kinda want it to be blueberry.
Your Friend: Huh? You are a crazy person.
You: I bet you 20 bucks I could find a place that would do it.
Your Friend: You're on!
