Dinner
From Memory Alpha, the free Star Trek reference
Dinner was the name of the main meal of the day, following breakfast and lunch.
In 2369 Jake Sisko was late for dinner with his father. The computer located him in cargo bay fourteen where he taught Nog in reading. (DS9: "The Nagus")
While trying to be polite, Kira Nerys told Aamin Marritza she didn't want to disturb his dinner shortly before she interrogated him. (DS9: "Duet")
