Every month Chili's updates their special $5 Monthly Margarita with a new drink, which is offered for $5 all month long.
November's $5 Margarita is the Hennessy's Harvest, an alcoholic drink that features Hennessy Cognac, Lunazul Blanco Tequila, fresh sour and Triple Sec.
The Hennessy Harvest is only available at Chili's until the end of the month, when a new $5 Monthly Margarita will take its place.
