Mellben Seafood is a seafood restaurant in Singapore's Chinatown area that sells chili crab and butter crab. The butter crab is eaten by dipping fried buns into the butter sauce, and the chili crab is paired with rice. It opens at 5 PM, and customers look at the live crabs first to choose the size and cooking method. At 7 PM the wait was 40 minutes, and going on a Saturday without a reservation takes up to 1 hour 30 minutes.
