We know at least one managing editor around these parts who doesn't dig Casa Navarro, which works for us; one less person crowding up the joint, which gets more and more packed 12 years after Blanca Navarro moved from downtown El Taxco up to Northwest Dallas, where this place has since become a fixture in a strip mall known for its discount, well, everything. Funny thing is, we didn't realize how popular the place was till two Yankees--which is to say, two guys we know who live in Richardson--told us it was on their spot of rotating regular eateries; see, Mr. Managing Editor, it is worth the drive. For what? Well, maybe the green-salt-rimmed top-shelf margaritas, which somehow always seem to help us wind down the week; or maybe it's the gratis pinto bean soup, which we're always tempted to super-size; or the chicken mole, which goes down like melted chocolate; or the basic Tex-Mex dishes always heavy on the cheese and light on the grease (or so we tell our stomachs?and hearts). And we dig the Christmas lights that stay up year-round; nothing cheesy about it, but have you tried the enchiladas?
