Eating seafood just feels so decadent. It has to be sustainable and incredibly fresh, which takes love and care from sea to plate. There's something of a fish frenzy in the capital right now and we've been eating our way around the new openings (all in the name of research, obviously) to give you our round-up of the best. Do you have a favourite fish restaurant? Tell us about it in the comments box below.

Angler, South Place Hotel, London
South Place Hotel is a hop and a skip from Moorgate tube station, and its Angler restaurant is designed for the suited and booted – think starched white tablecloths, smart service and city slickers. Choose from Cornish crab (£13.50), oysters (from £6 for three), Angler & lobster pie (£21) or, if it's pay day, the mixed grill (£26.50 per person) – a generous platter of langoustines, scallops and red mullet.

Bentley's Sea Grill at Harrods
A taste of Richard Corrigan's renowned Piccadilly restaurant, Bentley's, in one of the country's grandest food halls. Perch at the bar and tuck into Rockefeller oysters (£22 for six), a 'proper' shellfish cocktail (£24) or half a grilled lobster (£35) and the best soda bread, served with seaweed and organic butters. Heavenly decadence.

Fish Market at The Old Bengal Warehouse
Bringing a taste of the seaside to the City, Fish Market showcases British seafood in a relaxed and informal setting. Nibble on winkles and whelks (£6 for half a pint) or share a fish board of cod's roe, potted mackerel and smoked salmon with horseradish cream and pickled cucumber (£10.50). If you want to push the boat out (sorry!), oysters (from £7), langoustines (£7.25 each) and lobster (from £17) all feature on the extensive Crustacean Bar menu.

Simply Fish, Camden
Freshest fish and seafood, caught sustainably and daily in Cornwall, at affordable prices. Create your own dish for £12.50 by selecting a fish, a method of cooking, a sauce and an accompaniment.
