Borough Green High Street is the village street with the shops, a short walk west of the station on the A227 side of the settlement. Royal Fish and Chips is listed at number 62. The photograph is an arcade near the station from 2005. It is the town, not a labelled shopfront of the chippy.
If you are coming from Sevenoaks or Maidstone, you want Borough Green, TN15 8BJ, not Borough High Street in Southwark and not Wrotham village square. The station name Borough Green & Wrotham is a railway name. The shop is in Borough Green.
Walk notes are on finding the shop. Hours are on opening hours.
