I'd feel slightly self-conscious taking photos of this restaurant, but The Savoey, located in the Tesco Plus shopping center on Srinakarin is really consistently excellent and well-worth a visit. It serves top-quality Thai food with an emphasis on fresh crab and seafood which can be selected by the customer from tanks inside.
The restaurant is opposite Starbucks, just inside the shopping center, so it offers no enchanting vistas; it is modern and has two private dining rooms to accomodate parties. If location is everything, then the Savoey isn't for you, but it's a must for serious foodies.
