If Co. Cheese isn’t one of the first restaurants you hear about in Shanghai, you’re doing it wrong. This beloved little restaurant makes the best grilled cheese sandwich you’ll ever have. Choose from fillings such as Mac and Cheese, turkey and mashed potatoes, duck and brie, or Chinese style braised meat. A small sandwich is just RMB50 ($7), and at lunch that comes with a free side of tomato soup. Just what the doctor ordered.
