Apparently the best way for Dr. Strange, the Sorcerer Supreme, to hide his Sanctum Sanctorum for both the general public and the Hulk soldiers is to disguise it as yet another Starbucks location. They’re everywhere so it’s virtually unnoticable. As long as it stays under construction, no one will bother him.
In real life there are actually 9 Starbucks already located in that general vicinity in case you wanted to know. I used a Starbucks locator spell for that little nugget.
