Poseidon is a seafood buffet in Da Nang serving shrimp, crab, and steak. The spread centers on shrimp and crab, with cheese shrimp, cheese oysters, and steak cooked to order. Without a reservation, the wait can run 20 to 40 minutes; with one, entry is immediate, and payment is cash only. Water and drinks such as cola are billed separately, and birthday songs play repeatedly, making the room loud.
