Applebee's is serving $1 margaritas all of October.

The casual dining chain launched "Dollarita" on October 1. The promotion — which features margaritas on the rocks — will continue to the end of the month.

"We focus on our food a lot, but 'bar' is in our name, and it is an integral part of what makes Applebee's a great neighborhood destination," Patrick Kirk, vice president of beverage innovation at Applebee's, said in a statement.

Applebee's is doubling down on deals to attract budget shoppers and its history as a bar as casual dining sales have slumped. In August, executives announced that the chain plans to close between 105 and 135 locations this year.
