"The owners of Tzuco, lauded chef Carlos Gaytán’s Mexican restaurant, have turned their attention to Italian cooking and taken over the former Rockit space in River North. Ummo is decadent with items like pistachio-crusted lamb and ravioli with lobster-butter ragu. Chef Jose Sosa and staff are influenced by Italian, American, and other restaurants around the world and have created a unique menu that will frequently change." - Ashok Selvam
