24 Hour Supermarkets
Some supermarkets in Singapore have 24-hour branches, making them ideal for picking up local snacks and foods to bring back home. Over the counter medication such as Panadol (for pain and fever), cough syrup and antacids are usually available, and generally there are more choices than you would find at a convenience store.
Cold Storage branches and their respective telephone numbers, business hours and maps can be found on the Cold Storage website.
A complete list of their stores and their respective operating hours can be found on the NTUC Fairprice website.
