Ah, Sunderland! It's a grand tourist destination. Best fish and chips in NE at Lowries by the Puffing Billy in Seaburn. Best choice of real ales at the Kings Head in Detford. A fine environment for an invigorating stroll and a delve into English history via the Glass Centre and St Peters Church - once the home of the Venerable Bede. It's an empowering place (as long as you avoid the Stadium of Shite).
Newcastle, on the other hand, is a frightful place.
