Authentic Tex Mex in DallasIf you're craving Mexican food in Dallas, head to El Rey Del Grill. The no-frills tacqueria in the hospital district has a limited menu, but everything is done extremely well. The tortilla soup and the tortadas are particularly excellent. The owner is often there, and the service is very friendly. There's a good selection of beer, and the eatery is working on getting a license for BYOB wine.
