If you've got Mexican on the mind, a recent opening is need-to-know. Called ¡Una Mas! Mexican Grill, the fresh addition is located at One Market St. (between Steuart & Spear streets) in the Financial District.

This newcomer to San Francisco—which has other outposts in the southern Bay Area—specializes in fast-casual Mexican cuisine like soups and salads, quesadillas, tacos, and burritos. 

The restaurant, which officially debuted December 26th, joins other eateries at the One Market food space, like Cafe Elena, Osha Thai Express, and One Market Restaurant. 

On the menu, expect to see dishes like crispy taco salad with fresh romaine lettuce topped with black beans, shredded cheese, salsa fresca and guacamole served in a tortilla shell; and tortilla soup, with marinated grilled chicken, avocado, cheese, and tortilla strips. 

Tacos offer a choice of steak or chicken and black or pinto beans, salsa fresca, cheese or sour cream, while a "Taqueria Taco" has steak or chicken, onions, hot salsa, and cilantro. 

Switching over to burritos, there's the "Foghead" with chicken, barbacoa or steak with house-made BBQ sauce, cheese, guacamole, sour cream, black beans, rice and corn salsa in a tomato tortilla; and the "Gallito Griller," with a choice of meat, cheese, guacamole and salsa fresca. 

Rounding things out are drinks like fountain sodas, aguas frescas, and bottled beers. (You can check out the full menu here.)

¡Una Mas! Mexican Grill is now open at One Market St., so stop in to try it for yourself.
