Magnum Mania!

Does anyone know which restaurant Magnum was sitting in, when he was
searching for Mac, in the Season 5 episode, Mac's Back. Or was the scene
filmed in the Diamond Head studio? It looks like he is watching pedestrian
traffic overlooking Kalakaua Ave.

It's not a restaurant. The location is the 'C. Brewer Building' at 827 Fort Street Mall (at Queen Street, Downtown Honolulu).
Here some links about its history:

Thank you so much for your reply. My husband and I have only been to Oahu once
and visited a few of the Magnum PI filming locations. The C. Brewer building
hasn't been mentioned in the Magnum Mania forum. Of course, we have been to
Robins Nest and really enjoyed it.
