Taco Bell customers in Chicago can now have beer with their burritos and sangria with their soft tacos.

The chain opened a location that serves wine, beer, sangria and frozen mixed drinks in Chicago on Tuesday. It's a first in the U.S. for Taco Bell, which is owned by Louisville, Kentucky-based Yum Brands Inc. A similar location will open in San Francisco later this month.

The new restaurant will also feature trends Taco Bell says it is seeing among millennials: "tapas-style" appetizers, a mural by a local artist and an open kitchen.

"You will literally be able to see the food" before it's prepared, said Meredith Sandland, Taco Bell's chief development officer. "(Customers will be) able to see all the beautiful ingredients."

Aside from the alcohol and appetizers, Taco Bell says the menu will be the same as regular locations.

Taco Bell isn't alone in trying alcohol. To try and boost sales later in the day, Starbucks has also been rolling out wine, beer and small dishes at select U.S. locations. Chipotle also serves margaritas and beer, depending on the location.

It is just the latest evidence that traditional fast-food chains are trying to revamp their images to be more in line with changing expectations.

Whether Taco Bell can make the transition remains to be seen. In 2012, the company also introduced a line of Cantina bowls and burritos intended to compete with the Chipotle restaurant chain, but marketing for that lineup has since been changed to emphasize protein content.

In addition to beer ($4), wine ($4) and sangria ($4.50), the Taco Bell location in the Chicago's Wicker Park neighborhood offers "Twisted Freezes" — frozen drinks that have rum, tequila or vodka mixed in. The latter will come in Mountain Dew Baja Blast, Cantina Punch and Cantina Margarita varieties, and cost between $6.19 and $7.19.

The San Francisco restaurant will have beer and wine, but no sangria or mixed drinks. Taco Bell says it will be by AT&T Park and feature a patio and window where people can pick up orders. The company hasn't said exactly when it will open.

Taco Bell says the new restaurant concept reflects the "millennial trend of seeking more urban environments." Right now, it says the vast majority of its nearly 6,000 U.S. locations are in suburban areas, with less than 1 percent in urban neighborhoods.

But Taco Bell said it planned to add 2,000 locations in the U.S. over 10 years. And Sandland said "several hundred" of them will have the design catered to city streets, with a portion of those likely serving alcohol.

Restaurants that serve alcohol will be called "Taco Bell Cantina" and offer a "tapas-style menu of shareable appetizers." They include nachos, quesadillas, chicken tenders and rolled tacos.
