"As the name suggests, Champagne is the focus of this corner fixture, which opened its doors more than 35 years ago. River North denizens and visitors alike will find one of the largest collections of sparkling bottles. If the selection process ever seems daunting, turn to the team (many of whom have been there for decades), who can also offer guidance and food pairing recommendations. Make a reservation through Tock." - Naomi Waxman, Eater Staff, Ashok Selvam
