GUI (South Bridge) is a cafe across from Maxwell Food Centre in Singapore that serves Korean lunchboxes and Japanese dishes. Its signature item is the Rice Box, a shaken lunchbox with Korean-style toppings such as spam, seaweed, and egg, served in a traditional gold lunchbox tin. The space is decorated with cat-themed items and has wide indoor seating, and the cafe takes its name from its owner's cat. Matcha becomes sweeter when syrup is added, and a parfait is also on the menu.
