Stayed at the Regency Hotel, just across from the Kensington Hotel. This little cafe is just a couple of blocks away. I've been on a lifelong quest for the perfect pastry, and found it here. Great coffees too, and superb sandwiches with fresh made baguettes. Stop by in the morning for a pastry and coffee, and have proprietor Matthieu (really nice guy) make you sandwiches before you head out on the trains to Brighton, Bath, Edinburgh, or any of the other wonderful day trips accessible from London. Nice little neighborhood farmer's market on Saturdays. I think he's closed on Sunday.
