This is the bonus cache for the "Where can I go to get a burger around here?" Adventure Lab. The cache is not at this location. The location of the cache is
N 44° 27.ABC' W 87° 56.XYZ, where ABC and XYZ are revealed in the Adventure Lab.
In keeping with the subject of the Adventure Lab, the bonus cache is also in front of a hamburger place, but considering all the great hamburger places you visited in the Adventure Lab, I can't see why you would want to go there.
Congratulations Cache Couple 2 for being first to find.
