Not part of a set meal (1,2,5)
I believe the answer is:
a la carte
(Other definitions for a la carte that I've seen before include "Not table d'hote" , "'Menu with individually priced items (1,2,5)'" , "Menu with dishes listed and priced separately" , "The posh menu, pick what you like" , "Where dishes are ordered separately, not from a set menu" .)
