Lap up a little luxury at the members-only London Capital Club on Abchurch Lane. Tavern Steak & Oyster, their elegant restaurant and bar, is open to members of the public. Here you can stop in for, unsuprisingly, steak and oysters, but also chalk stream trout with Jersey royals, pan fried calve's liver and mac 'n' cheese (no doubt a fancy version).
There's a dress code for this place: smart business casual wear, although they do allow jeans in the Tavern.
