El Toro Loco

El Toro Loco occupies a unit at the western end of the Grassmarket, the historic market square below Edinburgh Castle that is now one of the city's busiest pub-and-restaurant strips. The format is Mexican street food: burritos, tacos, quesadillas, and enchiladas, with the kitchen slow-cooking meat each morning and making all beans, salsas, and guacamole fresh on the premises daily.

The menu accommodates vegans, vegetarians, and carnivores, and the spice levels run from mild to what the restaurant calls "crazy brave." Two dishes with toppings come in at around £12, which represents competitive pricing for a Grassmarket address where tourist-facing restaurants typically charge more. TripAdvisor rating is 4.0 from 339 reviews. Reviewers praise the freshly prepared food and the welcoming staff, with breakfast burritos and pulled-pork fillings singled out as highlights. The kitchen opens from 9am, seven days a week, covering breakfast through dinner — a fuller trading day than most Grassmarket competitors.
