"I stopped here during my lunch break at Nob Hill because the line was outrageous, seemingly operating on a single line system that only moved when someone became available. As I walked to my car, I noticed Una Mas, which was empty, so I decided to check it out. The prices were quite reasonable, so I ordered a margarita steak salad. It turned out to be better than I expected! The salad featured a fried flour tortilla on the bottom, filled with pinto beans and mixed greens, topped with minced steak and salty Mexican cheese (Cojita). The flavors were really impressive—definitely worth a try!"
