The Big Easy Bar, BQ and Lobstershack is one of a small London chain. It's bang opposite the famous Rules Restaurant in Maiden Lane. Food is BBQ style plus seafood; pre-theatre and late-night menus are available. No cask ale but a good range of craft keg beers on draught including their own house beer at the "jaw dropping 9 metre bar". You don't have to eat, but there is a bar bites menu if you want to snack rather than main-meal.
