Loop lunch spot focuses on fast, fresh, authentic Mexican fare.. In Short Business is mostly takeout at this casual Mexican cantina, but there are a few scattered tables in the colorful space. Taco Fresco emphasizes healthy aspects of the menu--lean meats, low-fat cheese, and fresh ingredients, with nothing fried. Choose from grilled steak, chicken, veggie, or tuna tacos, served with lettuce, pico de gallo, tangy Chihuahua cheese and rolled up in hearty corn tortillas. Grilled veggie quesadillas--stuffed with zucchini, peppers, onions and cheese--are a filling vegetarian treat.
