If you place yourself in the very center of the inner parking lot at 3175 Rutherford, Starbucks will be directly to the North, and the Day Spa (Unit 5) will be directly to the East located within the strip building there, and approximately in the middle of those Units.
Edit: In before anyone notices, I did not know the difference between East and West - oops. If Mliesend1 did not like, I would not have come back to see what I posted was incorrect, so shout out to him.
