Law and Lager
Seven Stars, a tiny pub opened in 1602, is a favorite of the legal trade given its close proximity to the Inns of Court and the back of the Royal Courts of Justice.
During the week, you may see barristers in their wigs and robes dropping by for a pint in between court sessions. The landlady is known for her temper and woe betide you if you question the menu or ask for a latte (it's espresso or nothing). Now that you've been warned, avail yourself of a sandwich and a beer as this is one terrifically atmospheric pub.
If you want to take a look inside the Royal Courts, a majestic building where you can view a fun exhibition of legal costumes throughout history, it's a simple matter of walking in. There's some airport-like security, but it's efficient and quick. Also, there are public toilets inside.
