Overlook Hospital is carved into the mountain. For that reason our ground floor (the main floor) of the front of the main building is the fifth floor. The rest is underground.
We have a main corridor underground that winds for 1/4 mile.
So, the main entrance is to the fifth floor.
Entering on the 5th floor, you are in the main lobby.
We are hard to find THAT way! The 5th floor is nice, but that's NOT us. We are in the West Wing.
Easier to go back outside.
