Albion, Bankside Café, British Food and Drink in London (southwark or London Bridge) - this is where I pick up my daily bread when I'm in London (and when the market … Borough Market … is not open). Its a great cafe. I recommend.
If I only have time for one real dinner in London--which is usually the case in between Fashion Week parties--it will be at the Tramshed in Shoreditch. How will I choose between the steak and the chicken? (See August Conde Nast Traveler for a scrumptious description.)
