Hehe, sounds like it was quite a night out then! My first question would be which Tube are you thinking of? If it was Holloway Road, then I am pretty sure you're talking about Big Red (rock pub at no. 385) but if it was Angel then I'm not so sure where you've been. I hope others can help - will tweet...
If it was Holloway Road it would either have been The Big Red or The Gaff (sadly deceased due to ruddy corporate coffee shop chain).
If it was Islington then the Mucky Pup or Slim Jim's Liquor Store.
All of the above are fantastic with wicked Juke Boxes and good booze.
