From an away perspective, one good thing about Newcastle is that, although a few probably do, I'm not sure, the majority of pubs couldn't care less if you're an away fan or not. Obviously, for certain fixtures they will enforce a door policy but for your average away fan from further south than Middlesbrough, you can go in just about any pub in the town, even with a shirt on.
When I went to Spurs a couple of year ago, it's in a busy part of London with loads of pubs around... but none of them will fucking let you in.
