There is a little Mexican place on Church Avenue and about E. 8th Street in Brooklyn, filled with Mexicans eating and taking out. I'd like to try it. The sign outside promises Tijuana-style (sic), and so I'm wondering what that should promise me. And a list of tortas--what would I desire in an authentic torta? (See the bagel discussion--Eric Eto's description of the ur-bagel is what I'm talking about here, re this part of Mexico, its tortas, etc.) Thanks.
