Danny’s Traditional Fish & Chips is at 5 The Parade, Coulsdon Road, Old Coulsdon, Greater London, CR5 1EH. The pin is in Old Coulsdon, in the London Borough of Croydon. Tripadvisor files the listing under Croydon. That is the borough, not East Croydon station.
On the road
Coulsdon Road is the A23 spur through Old Coulsdon. The Parade is the short shopping frontage, not the Coulsdon South railway approach and not Coulsdon Town. Use CR5 1EH. A listing that prints CR5 2PS is a different pin.
By public transport
Buses along Coulsdon Road serve Old Coulsdon. Coulsdon South and Coulsdon Town stations are a ride or a walk, not a doorstep. If you are still on a platform at 20:50, look at the listed 21:00 close before you phone a large order.
Open the pin in Google Maps. If the label says Danny’s Fish & Chips or Danny’s Chip Shop, that is the same counter on Facebook.
