The myriad charms of Rock Hill Tex-Mex establishment Nachomama's are not hard to understand. It's easy to fall under the spell of the joint's unassuming but spot-on ambiance: the vintage country & Western on the radio, the beer- and soda-logo tabletops, the rainbow of fruity Jarritos sodas. And that's before you even get to the menu — the burritos, quesadillas and especially the fajita tacos are all justly adored. It may not be the first item that comes to mind when you're in a hotbed of chalupas and flautas, but Nachomama's rotisserie chicken, normally the province of supermarket delis, is worth the trip in its own right. Available as a quarter, half or whole, the bird comes out tender and juicy, providing a depth not normally associated with most Tex-Mex dishes, smothered as they are in cheese and/or sauce. A plate of chicken comes with rice, beans, shredded cabbage, grilled onions and tortillas, plus your choice of salsas. Try finding a spread like that at a grocery store — or at Chipotle or Qdoba, for that matter.
