My wife and I were living in the heart of Hispanic community near Ft. Collins, Colorado. One day we just had to have taco bell. The value meal that's $13 in the midwest was around $22. We abandoned the plan. The taqueria makes better gringo tacos for $2ea be it in Colorado or the midwest.
I didn't really have a point. I guess it's to explore your local taqueria. If the only proficient english language speakers are high school age or younger then you've found a solid joint.
