Once tucked away on West Davis Street in Oak Cliff, the original Gloria's served up some mighty tasty, traditional El Salvadoran meals. Now, 25 years later, the tiny, family-run business has erupted into a local institution with 13 locations, in DFW and Austin. Just this year, the original Oak Cliff location at 600 West Davis St. closed its doors for good and moved its staff down the street into the historic Fire Station No. 15. Sure, the station has been renovated, but it still has plenty of fire-station charm, including a pole that splits the upstairs and downstairs dining rooms.
