Deliciously Cheap Burgers in Billings

MSN had deliciously cheap burgers in all 50 states.  Good info for the next road trip.  When they selected the cheap burger in Montana they didn't pick a place in Billings but Missoula instead.  To MSN I say, Hey, we've got cheap delicious burgers here in Billings too.

Who's got your favorite?  Sandee's and King's Hat came to mind right away.
