Stalking the Definitive Hamburger

I need to put in my vote for The Lion's Tap in Eden Prairie, MN (suburb of the Twin Cities).  They serve around a dozen varieties.  Nothing fancy, but the burgers are fabulous.  A tip: the price on the menu board is fairly high, but the Star-Tribune TV guide on Sundays always has a 2-for-1 coupon, as do the two weekly papers serving the southwestern Twin Cities.

Here in Colorado, Conway's Red Top in Colorado Springs is pretty good, too.  The burgers are absolutely enormous.  Any suggestions for good burgers in the Denver area or northern Colorado?  The Springs is too far to go for even a very good burger.  Thanks.
