Ponto Final is one of Cacilhas's most talked-about restaurants, tucked into the riverside just past the more prominent waterfront eateries. The terrace juts out over the water, and the tables closest to the edge are so near the Tagus that you can watch the ferries pass while you eat. The setting is unusually intimate for a riverside restaurant, and the kitchen is confident with traditional fish dishes.
The grilled horse mackerel (carapau grelhado) is a benchmark here — simple, fresh, and honest in the way that only works when the fish is genuinely good. The wine list leans on Portuguese regionality; the staff are helpful if you ask for guidance. This is the kind of place where lunch can extend well into the afternoon without anyone minding.
