The Styx is a seafood restaurant at 272 Wakefield Quay in Stepneyville, Nelson, in a large building overlooking the Tasman Sea. It opened in November 2012. The menu runs from breakfast through to dinner and desserts, with seasonal dishes and daily specials, all cooked from scratch. Dishes include fish of the day, scallops, tiger prawns, mussels, calamari and tartare-topped fish. Its seafood chowder is one the restaurant says some guests call the world's best.
Fresh fish is delivered several times a day, and the bread is baked daily. The restaurant works with local dairy, fish and meat suppliers. Groups of six or more should phone, and everyone, adults and children, should be counted in the booking. Online bookings close three hours before service, so for a table on the day, call. Email is for groups of 15 or more booking more than 48 hours ahead. The Styx also hosts functions, with a private bar, from 15 to 170 guests and more than 200 each year.
