Chupadinha is one of Natal's most popular seafood restaurants, concentrated in the Ponta Negra area. The name refers to the local style of sucking the sweet meat from small crustaceans — a technique that tells you something about the style of cooking here. The menu centers on lobster, shrimp, crab, and fish cooked simply and well, and the portions are substantial.
Reservations are recommended on weekends. The atmosphere is casual and noisy in the way that good Brazilian restaurants tend to be. If you eat lobster anywhere in Natal, eat it here — the northeastern Brazilian lobster is sweeter and more delicate than the North Atlantic variety, and a well-cooked one from this stretch of coast is one of the better meals you can have in South America.
