Im working near by, and often take my Break in this shopping center
So many choices, Burgers, Slurpies, $6 Coffee, sushi, Boogers, ect. it's all here, and a Cache to make it complete.
All you have to do, is find out which Booger has the Cache, there are Four of them, so it shouldnt be tooo hard 
Please No Spoilers in your logs
Happy Hunting!
