Sankey's The Old Fishmarket
Serving the best of British seafood, as well as an extensive choice of champagne and sparkling wines, this intimate little restaurant has bar seating set around an open kitchen, so you can watch (and chat with) the chef preparing your food. But don't let the relaxed, friendly, and unstuffy atmosphere fool you; this is exceptional quality, fresh seafood cooked to perfection (or not cooked at all, in the case of the delicious oysters). Order from the catch-of-the-day specials pinned up above the bar, from the à la carte menu, or from the special oyster menu: it's just £1 a shuck every Friday between 4 and 5 pm.
