This restaurant, pronounced phot saphaa khaan, is famous for its cook, who is the relative of a former cook in the royal palace. The restaurant, which has been located in the same place since 1925, claims to follow these royal recipes, and serves excellent old-school faves such as mee krawp (sweet/sour crispy noodles) and kaeng liang (a thick soup combining shrimp and vegetables). I particularly like the more unusual dishes such as a delicious salad of fresh herbs and grilled pork, and the deceptively simple but delicious omelet with lemongrass (pictured above).
