"Rick Bayless is the Oklahoma-born chef who obsessed over Mexican cuisine, appearing on TV and creating his own grocery-food empire, and his restaurants still remain landmarks in River North for their inventiveness. His flagship, Frontera, which opened in 1987, provides a more casual dining experience, while sibling Topolobampo, which opened two years later, was one of the first restaurants in the U.S. to present Mexican food in a fine dining atmosphere. Bar Sótano is the baby of the group, a basement tavern that serves as an experimental space with pop-ups and creative cocktails. Bayless’s name often prompts emotional responses when it comes to discussion about cultural appropriation, but there’s no question that he’s raised the appreciation for Mexican food in America. (Fast-casual Xoco, which has been spun out into the Tortazo chain, is in the same building.)" - Ashok Selvam
