London

Not very close to you but if you are up in North London at any point check out the Faultering Fullback. Cool bar with awesome multilevel courtyard. Awesome Thai place in the back.

I lived in Islington for 6 weeks and The White Lion was right around the corner from the dorm. Good beer on tap and nothing but locals. There's also a good Indian restaurant right around the corner. You can get off the Tube at the Angel Station and there are a ton of touristy bars lining the street. The White Lion is much more of a local hangout.

This is quite vague, but alongside the River Thames there are quite a few boats that are actually bars. Pretty sure the place I went was was called Hispinola near Embankment tube station.

You can grab a meal below deck then sit on the boat with a drink. At night its really good as you have a view of the Houses of Parliament, the eye etc. all lit up in the night sky.

If you are by yourself there are usually some smoking hot womenz there, and if you are with a wife/gf etc. it can be romantic(actually found out its where my dad took my step mum on their first date), although its not somewhere to go with kids.
