Chipotle Mexican Grill (NYSE:CMG) has a plan to boost its moribund comps.

The fast-growing restaurant chain will be adding premium margaritas -- handmade with Patron silver tequila, triple sec, agave nectar, and fresh lime -- to more than half of its restaurants next week.

These drinks won't be cheap, priced between $6.50 and $8 apiece. 

The allure may be obvious. Average ticket prices could head higher as customers trade up from sodas and beers. However, McDonald's (NYSE:MCD) also thought that it could boost sales and woo new customers by adding premium beverages. It hasn't exactly worked out well lately. Comps turned negative in October for the first time in a decade, and customer complaints are growing.
