. . .With Los Tacos No. 1 setting up in Chelsea Market, there’s about one thing to say on behalf of taco-crazy New Yorkers when it comes to defending their assertions that they now have one of America’s best tacos: God help you. West Coasters who haven’t even sought out the city’s best will likely have too much of a chip on their shoulder to admit it, many so-called East Coast taco experts haven’t a leg to stand on to combat the cliché that there are no good New York tacos anyway, and it’s going to seem pretty outrageous to declare a place open for less than a year as one that serves one of America’s finest, so good luck with all that. But who cares anyway? Texans and Californians be damned, it’s true. Los Tacos No. 1 serves a taco so good that you could dare anyone to taste it blindfolded against their supposed classic favorite confident and they’d secretly be worried they’d choose Los Tacos No. 1 instead. And Californians and Texans should have no reason to begrudge them anyway — it’s a collaboration of three close friends from Tijuana, Mexico, and Brawley, Calif., for crying out loud, guys who heard the East Coast plight and wanted to proselytize the West Coast expertise. Forget reason. Let’s go to taste. You really can’t go wrong whether you go with adobo or pollo, but the winner is the red chile-marinated pork, the adobada. Moist. Salted. Flavorful. Sweet but not cloying. Accoutrements. Proper moisture and accurately delivered tortilla. There are expertly prepared salsas. Dress it yourself. You’ll shut up because your mouth will be full and you will be happy. (You shouldn’t need to undersell them New Yorkers, but like dealing with that difficult friend, loved one, or sibling, you know well enough that introducing your West Coast friends to Los Tacos No. 1 will mean bumping into them there getting their fix.). . .
