We love our Metropolitan Cafe upstairs at Bloomsbury, New Bond Street. Serving perfectly brewed teas and coffees (a strong latte is a welcome wake up call in the office!) and beautifully handmade cakes, biscuits and treats. With a super tasty veggie menu with daily specials you'll never be stuck at lunch time.
We found this lovely little write up of the Metro over on A Rose Beyond the Thames (link here!), a lovely blog of reviews of the wild and wonderful.
