"Sotano" literally translates to basement, so this spot beneath River North’s Frontera Grill has a fitting name. The underground bar is an enjoyable place to hang out solo or with a small group, and drink interesting takes on margaritas. Like the seasonal carrot and habanero option that’s thick and sweet and spicy, or the complex tacos al pastor made with chorizo-infused mezcal. This drink kind of feels like you just took a sip of a margarita while mid-bite in a taco. It’s funky and strange in the best way possible, and you’ll keep drinking to try and figure out what the hell is going on. " - john ringor, veda kilaru
