I finally had the chance to try Rick Bayless's XOCO in River North and I loved it! XOCO means "little sister" in the Aztec language and it truly is the come and go but high quality sibling of Topolobampo and Frontera. It features street food like tortas and caldos, snacks like churros, pastries and chips with guacamole, breakfast tortas and chilaquiles, and mexican coffees and hot chocolates.
Food and drink is superb. The torta sandwiches are made with LaBrea bread and filled with excellent ingredients like Gunthorp Farms chicken, Prairie Fruits Farm goat cheese, braised Tallgrass short ribs, smoked Maple Creek pork loin and bacon, or wood-roasted suckling pig. They have four wine choices: Bodega NQN Picada 15 white blend, Verdad Albariño, Santa Julia Tempranillo and Qupe Syrah. They also offer craft beers, housemade soft drinks and complimentary water- still or sparkling.
