"Frontera has been in River North since 1987. And even though it’s way past the point of “hot and new” it’s still a good option if you’re looking for Mexican food in the neighborhood. Particularly things like enchiladas, tacos, carne asada, and moles—which are all done very well. The brightly colored space is casual, the service is always friendly, and they have a cute sidewalk patio that’s great for people-watching." - adrian kane, john ringor, veda kilaru
