EDIT: I am quite surprised that no one could identify this one, as it is a true Lincoln institution. What other Mexican restaurants in town offer pickled hot veggies and hot sauce in plastic cups, and serve their food on styrofoam plates? D'Leon's of course! Specifically, the 48th and Vine street location. Pictured here are a couple of their fish tacos, albeit with hard shells and not the more typical soft tortillas.
I should note, even Mr. Wilson couldn't identify this one correctly; his first guess was Fuzzy's (I finally relented and told him the location after his incessant prodding/begging to know the answer).
In anycase, the quest for the pogo continues.
