I have eaten tacos in Austin, El Paso, Elle Aye, and Albuquerque. I never said they weren't good. I said they weren't the best I had. Top 10? Probably.
Would you be even more upset if I told you the best I ever had was at some corner store at a four way in the middle of a field near Alma, Michigan thirty years ago? They were proper Mexican and all they served were tacos to the migrant workers there. I felt brave one day and I have been striving for that excellence ever since.
Tampa has some good trucks. Of the four cities I listed above, Elle Aye is the worst of them. El Paso probably the best. Austin and Albu are toss-ups.
