St Stephen's Tavern

You're drinking where Churchill once held court and modern MPs still slip away from Parliament for a swift half. This Victorian boozer sits directly opposite the Houses of Parliament, its ornate carved bar and etched glass windows having witnessed more political intrigue than most government buildings. The kitchen does justice to British pub classics – think proper fish and chips with mushy peas, slow-cooked beef and ale pie, and a Sunday roast that draws queues down Bridge Street. Yes, you'll pay Westminster prices (mains hover around £16-20), but the location and atmosphere justify every penny. Book ahead if you want a table with a view of Big Ben, though the buzzy bar area captures more of that authentic parliamentary watering hole spirit.
