"Some of its food markets rival those found anywhere else in the world. A favorite is Borough Market, the largest in the city, tucked away south of the Thames —walking distance from the Tower Bridge and Tower of London. Families love sampling from a variety of stalls or shopping for incredible picnic fixings to take to the Southwark Cathedral grounds nearby."
