Please note they are only opened during weekdays. You do not need to exchange pass to visit Nikon on the 4th floor. Visited on a Tuesday morning and was served by Michelle. Had a very seamless and pleasant experience sending in for sensor cleaning for my D750. It costs $32.70 and takes 2 hours, however mine was done in 1 hour due to off-peak. Very satisfied with the fast and convenient service by Nikon and great customer service by Michelle. :)
