The Berghoff is one of Chicago's oldest restaurants (if you don't count when it closed briefly and then re-opened) and once you step into this German place, it'll feel like you've stepped into the past with the dark wood, stained glass and gold lamps. It's no-frills atmosphere and service will appeal to those who are more interested in what's in front of them than surrounding them. Gluten-free items are clearly marked on the menu and include many German favorites including kartoffelsuppe mit thuringer ( a Munich-style potato soup with smoked thuringer) and sauerkraut. Diners won't have to skip desserts since the Salty Caramel Cheesecake and flourless chocolate cake are gluten-free, too.
