DinnerBell

Plays a sound when someone puts down a feast. Supports MoP, Cataclysm, and WotLK stat-increasing feasts, as well as the holiday Bountiful Feast. The sound will play even when you have the normal sounds turned off. The sound is from Ogri'la dailies; you can preview it with this:

/run PlaySoundFile("Sound\\Doodad\\SimonGame_LargeBlueTree.wav", "Master")

Very helpful so you don't miss Feasts in raids, or accidentally put down a second one!

Intentionally does not work in combat, to avoid any concerns about performance for watching the combat log. (One extra mod watching your combat log is harmless, but a dozen might be noticeable. But I don't want DinnerBell to contribute to this, so it doesn't watch the log during combat.)
