Old School RuneScape uses the British convention for floor numbering: Ground floor, first floor, etc.
A Premade fr' blast is a drink that can be bought at Blurberry's Bar in the south-east corner of the first floor of the Grand Tree. Premade drinks cannot be used in the Gnome Restaurant minigame.
Pineapple punches and Fruit blasts and premade versions are the only gnome cocktails that does not affect stats.
