The cluster of marisqueiras, or seafood restaurants, in the center of Matosinhos out in Porto's western seaside suburbs, are a magnet for fish-favoring foodies from around Portugal. Seemingly little changed since it opened in the 1970s, this place features a bar area—where locals snack on stools, hemmed in by glass tanks filed with crab and lobster—and a dining room out back that's a favorite with the Porto wine trade. The menu features a long list of ultra-fresh shellfish—from cat-sized rock lobsters (lagosta) to gnarled goose barnacles (perceves)—by the kilo; catch-of-the-day fish waiting to be slapped on the grill; and regular dishes of the day from the Porto cookbook. Sundays will feature bacalhau à Zé do Pipo (salt cod baked with a mayonnaise crust), Mondays and Saturdays, a formidable tripas à moda do Porto. Look out too for seasonal dishes like shad (savel) or lamprey (lampreia).
