If you're in Camden, I can thoroughly recommend The Sheephaven Bay - great pub, great food, great atmosphere, great for live footy and a huge Gooner pub... but with no threat of violence or intimidation ever.
Potentially. If I do, will either be at The Horatia on the Holloway Road, or The Gunners pub which is kind of inbetween Finsbury Park station and the Emirates, ikn a long-roundabout way. Both will have great atmospheres. If it's dry weather, i recommend the Gunners, Big TV screen outside and they usually have hot food stands in the beer garden, jerk chicken, burgers, hot dogs etc...
