TOD -
The tacos I had in Nogales with machaca and avacado. They were yummy!
There was a place in Phoenix, can't remember the name of it now, but they had Mexican seafood and had this great shrimp on french fries. It was dripping in garlic butter and would probably make me sick now, but I loved it when I lived in Phx in the 80s.
I like most Mexican food. I prefer Sonoran style to the Tex-Mex or New Mexico- Mexican. They are so hot that you can't taste the food and have numb taste buds the rest of the day.
