While "Bartender 93" might sound like a new viral game or a trendy app, it actually refers to a specific, legacy version of one of the world's leading industrial software suites: by Seagull Scientific.
Download a pre-made for VMWare or VirtualBox. Install Bartender 93 inside that. It runs perfectly and feels exactly like 1995. You can then "pin" the VM to your taskbar for one-click access to your cocktail library.
