FishWorks Restaurant & Fishmongers is a seafood restaurant on Marylebone High Street in London, entered past a fish shop at the front. Specials change based on the fish that arrives that day, and oysters, sea bass and halibut are cooked simply. Fish and chips come with tartar sauce and chips, and bouillabaisse is also available to order. The oysters can have grit or arrive in a disappointing serving state.
