The Anchor and Hope sits on The Cut in Waterloo, between the Old Vic and the Young Vic, which sets the rhythm of the place. It is widely credited as one of the very first modern London gastropubs, and the kitchen still cooks the generous, modern British food that built the reputation. The Top 50 Gastropubs list has long included it.
The catch, and the charm, is the no-bookings rule for dinner. You arrive, you put your name down, and you wait in the bar with a pint until a table opens, which can take around an hour on a busy night. Come for a long lunch, a pre-theatre sitting, or a patient evening over good cooking. Skip it if you need a guaranteed dinner reservation, because that is the one thing it will not give you.
