Helmed by “Top Chef Masters” winner Rick Bayless, one of Chicago’s most famous chefs, Frontera Grill is one-third of his trio of modern Mexican restaurants in River North. Frontera Grill accepts few reservations, allowing for walk-ins – so arrive early to secure your table. The menu features approachable Mexican-style home cooking and Mexican street food with fresh local, seasonal ingredients. Try a street food sampler and then move on to a mole and end your meal with a round of thick Mexican hot chocolate.
