Tall, narrow, corner pub, close to Parliament Square, and rebuilt in the late 1890s. The name is ancient, and a brewhouse named the Red Lion very close to this site has been dated back more than 500 years. The present Grade II listed pub retains several original features from its rebuild including a carved mahogany bar back, a patterned ceiling, and etched glass to the rear. Spot the portraits of former prime ministers in the main bar; there is also a cellar bar and an upstairs dining room.

Following a makeover the pub became part of the Fuller's Ale & Pie chain. There are three handpumps on each part of the bar. Unsurprisingly given its tourist and parliament location this pub is often crowded. Breakfast is served at weekends in summertime but no alcohol before 10am on Saturdays or noon on Sundays. The extensive food menu inludes not just pies, but other pub favourites plus sandwiches, and small plates such as haggis scotch egg.

The pub was honoured in 2022 on the 25th anniversary of National Pubwatch, when it was featured on a special commemorative coin. A previous licensee, Raoul De Vaux, had been a co-founder of the organisation.
