The Señor Roy's Taco Patrol menu is simple: Choose a meat to add to tacos, a burrito, a quesadilla, nachos or taco salad. Then add any of a number of salsas and extras. If you're not down with the unpredictable availability of mobile eateries, that's understandable, though they'll be less unpredictable with City Council recently voting to start a pilot program zoning off areas downtown for food trucks.
