The address is 2555 S. Lenox, Milwaukee Wi, 53207
Officially its at the intersection of Lenox and Otjen (how do you pronounce that?)
But Potter is the street that intersects KK and goes in front of the McDonalds.
I have been experimenting with driving routs, from the freeway its easiest to go down to Becher (even when you are coming from the South) and go over to KK, its a longer distance but quicker.
From the Chase I take Oklahoma to Howell, then North to Potter/Russell, its an odd left turn to stay on Potter and crossing KK is a bit tricky.
With the big truck I take Oklahoma to KK and KK to Potter.
If you drive down the alley watch for cars coming out of Siegel's, its a blind corner.
