The single best sandwich shop in Middlesbrough is Hungry Jack's. Freshly made, decently-sized sandwiches (a choice of about a dozen fillings) plus none, any or all of eight salad ingredients for £1. They will try to upsell you into including (non-free) cheese, coleslaw or "three cakes for a £1" and you do get far more salad than filling, but they have a really efficient, good operation going on and the quality is a tremendously pleasant surprise. It's a chain operation with close to a dozen operations around Teesside. Were I responsible for freak-of-nature-accident retail booms then they would be bigger than McDonalds, only more ethical.
Lots more to write, but not tonight. :-)
