From Monkey Island wiki
The Chef of the Scumm Bar is a semi-notable side-character from The Secret of Monkey Island who occupies the bar's kitchen, only leaving it to ask what the patrons of the bar want. In the game Guybrush has to sneak into the kitchen when the chef is in the front room in order to get the useful inventory items therein.
The Chef is a friend of Otis and during his imprisonment he sneaked food to jail; mostly pork trimmings and rump roast (with tails).
He can later be found crying at the Scumm Bar when LeChuck kidnaps Governor Elaine Marley and scares off all the customers. If the player talks to him he will state the obvious: where LeChuck is hiding, what the player has to do in order to get there and why he has to do it. As the player leaves the Chef will give him some heartfelt advice and start crying uncontrollably.
- "Why? For love, old boy. Don't try to hide it, it's written all over your face."
