Olive Garden is an American casual dining restaurant chain specializing in Italian-American cuisine.
Lois shows a fondness for the Olive Garden's breadsticks in "Lethal Weapons".
The Olive Garden's slogan "When you're here, you're family" is co-opted by the coast guard in "Veteran Guy". It is repeated several times, which leads to multiple cutaway gags of Peter and the guys gorging on pasta, after which on one occasion Peter complains that it is too salty.
