The Rusty Barnacle is a pirate-themed restaurant.
Originally it was only mentioned  but later appears when Eugene Fisk holds his bachelor's night. Also attending is Homer, Lenny, Carl, Charlie, Mr. Fisk and April Flowers. Meanwhile, Marge takes Bart, Lisa and Maggie to The Rusty Barnacle too. It is implied that the food is not prepared well, as Bart ended up becoming sick from witnessing his order of squid with extra tentacles.
- Ironically, both of its appearances were in episodes that dealt with infidelity.
