In order to get the Prima Vista miniature
Firstly, You get to accept the side quest just before reaching Dali for the 1st time, enter the Observatory Mountain next door. Talk to Morrid the old man in the building, he is looking for 3 rare coffees, Moccha Coffee, Kirman Coffee and Burman Coffee.
- Moccha Coffee can be found at the South Gate near the Chocobo Forest, search next to the water on the right hand side at the front. You can get this Disks 1,2 or 3, but I got it in Disk 1 before heading to Burmecia.
-Kirman Coffee can be found at Madain Sari on Disk 2. After the Eiko meal event check the left side of the kitchen, there will be a bunch of supplies nearer to the screen than the table, look there.
-Burman Coffee is the hardest one to get in my opinion. On Disk 3 after Garnet/Dagger is about to ascend to the throne, the party heads to Treno. Leave Treno and follow the path left to the Gate and through the area with the Gate Pass back to Dali. Once in Dali enter the Mayor's house (before now he tells you to leave, but now he's not there, just the sleeping child), this is the hard bit, you have to press the desk 3 times until the child has the zzzz speech icon, then choose the heater. You will receive the Mayor's Key. Head north and enter the windmill and use the Mayor's key on the door, leading outside to the chocobo. Go to the far end and hidden there's a treasure chest worth 30,000 gil to you, press it again, the prompt is now a question mark and you will receive the Burman Coffee
After receiving the three, assuming the Burman Coffee is the last one you get. Cash it in straight away. Travel from Dali to the Observatory Mountain and Morrid should be outside on the steps (was for me). Once you have pressed to talk you be straight back in his house and after one cut scene. Pop goes the trophy.
