Q: When is a tortilla more than a tortilla? A: When it comes from the Frontier. This Albuquerque institution teems with New Mexican staples, including huevos rancheros, signature sweet rolls, and all things green chile. Open 24 hours, it caters to students, locals, and truckers alike. And those flour tortillas? Says co-owner Larry Rainosek, “Our recipe is just a little bit better than other people’s recipes.”
