So I'm off on a trip that'll take me from London to Newcastle/Sunderland to Glasgow and back. Any tips for places in any of these spots or points in between would be much appreciated. Looking less for haute cuisine than for casual, inexpensive stuff. And okay food in a pub with exceptional atmosphere would be fine. (None of these locales are renowned as chowhounding hotspots, so I don't ask for much.) London's been covered on this board previously, but I have one specific question: any standout fish-and-chips spots? Another specific question: is eating haggis a good idea?
