2 different nights we went to restaurants in the Banglatown part of the Tower Hamlets Borough of London. That area is named for the high concentration of Bangladeshi immigrants and has the greatest concentration of Indian, Pakistani and Bangladeshi eateries in the city. All over the place the metal doors that cover shop windows at night and the walls, etc. had wonderful vibrant art on them. It is another area I could probably spend a week in taking pictures.
