Tuesday is Margaritaville

White button with black and white outlined green text. 

“Tuesday is Margaritaville” was an advertising slogan used by now-defunct Mexican chain restaurant Chi-Chi’s.The chain’s lounge (or “cantina”) was referred to as “Margaritaville,” and this button is related to a two-for-one margarita special offered there on Tuesdays.

The cantina shared a name with a hit song by Jimmy Buffet’s, recorded in 1977. When Chi-Chi’s attempted to register a trademark on the “Margaritaville” in 1985, Buffet successfully opposed the registration, citing that fact that the popularity of the song meant that its title was virtually synonymous with his public persona.
