Ruben Beltran, who worked for years with Rick Bayless at  Frontera Grill, has opened Maya del Sol, his own spot in Oak Park, in the space once occupied by the late and not-at-all lamented Slaton’s Supper Club. A more complete review is forthcoming, but on our first visit, we concluded: it rocks! Though I was ready for missteps in what superficially seems a trendy scene (by Oak Park standards), the food struck me as authentic and delicious. Cochinita pibil, the pulled pork in achiote from Yucatan, was served with requisite pickled onions and house-made tortillas . . . and thus my heart was stolen. There are also nuevo Latino options, like perfectly prepared salmon in light sauce and nachos covered in pot roast (!). Cocktails include a pan-American range of pisco sours, caipirinhas, mojitos and others. This is one to watch. 144 S. Oak Park Ave, Oak Park, 708-358-9800
