i've found the three coffees and decided to tell everyone about them just incase anyone wants some tips.
1. one is in the south gate by lindblum right after you get freya and vivi at the festival of the hunt.
2. one is in madain sari in eiko's kitchen behind a picnic table.
3. last one is in dali. go right before the card tournament in treno(the big official card tournament). in the mayors house there will be a sick person lying on the bed and you have to play a mini game to get to some useful items and eventually the mayors key. go right outside (by the entrance to the undergroud) and put the key in the big door. there will be a chest that contains around 30,000 gil. after you get the gil, check the chest again for the burman coffee.
HAPPY HUNTING!!!!!
