The cinder block exterior of the former Dairy Queen on Colorado Avenue looks even more drab in green and orange. But don’t be fooled. I’ve been pleased after three visits to Los Carnales — for the food, yes, but even more so for the price. You can get two tacos, intriguingly folded and crispy, for $2.75. How about a pair of enchiladas for $4.25? Or a guaranteed-to-fill burrito for $5.50? The menu is endless. The drive-thru gets busy for breakfast.
