One of Singapore's oldest seafood restaurants, Red House Seafood has managed to keep up with the times. While it has outlets in the trendy parts of Singapore, it is the latest waterfront restaurant at Esplanade that stands out. Placing an emphasis on sustainable seafood, the owners still source their meaty mud crabs from Colombo, Sri Lanka, which come cooked in a variety of styles. Its chilli crab is a prime example of how the dish should be done: sweet, tangy and spicy all in one bite.
