4 stars for a great breakfast, fast service, and beautiful interior. Came for English breakfast before visiting the British Museum. We found seats and were served promptly. Service could have been a bit more friendly, but can't complain about the efficiency! Breakfast was delicious. They have a vegetarian sausage option with the English breakfast, which was very nice. The bread was super good. Could have done without the Americano: a bit acidic. Wish the waiter were more attentive during the meal.
