I may be wrong, since I haven’t been back to the old neighborhood in about 20 years, but Mozza’s may be located in the old Dirksen’s Pharmacy building near the corner of Melrose and Highland. I remember the large apothecary bottles filled with colored water.
When I was about ten the pharmacist gave me a Voigtlander 35mm camera that I eventually took apart on our dining room table with a jeweler’s screwdriver from my Dad’s toolbox. Tiny little springs and screws flying everywhere. I actually got most of the parts back together and the damn thing worked.

I’ll have to stop by for a pizza sometime…
