Greaser's Cafe was a 1950s-themed diner that the Simpson family once went to.
The diner served 1950s-themed food and the tables are designed to look like cars from the 1950s. The restaurant did a dance competition every night, and the prize for the winners was a Harley Davidson motorcycle. Homer and Marge once competed in one of the restaurant's dance competitions and won the motorcycle. However, three days after the Simpsons won that competition, Greaser's Café went out of business.
The restaurant has two known bathrooms, labeled "Squares" and "Cool Cats", both of which seem to be for women, for some odd reason. Jay North appeared at the restaurant as his character Dennis the Menace.
