Ok well i recommend u go upto the area I live. When u get to Kings Cross station get the tube to Angel station. Its one stop on the Northern Line. Once u get out of the station take a look around. There are countless pubs, bars etc. Most of them will be to ur right on the opposite side of the road. There are probably in the region of at least 70 pubs and bars and resturants in the area.

Other than that, covent garden is the place to be. I guess it all depends on how many pubs u wanna go to...

btw if u do go, and u find urself in the Lloyds bar, I used to work there, so no loudmouthing lol

edit: now why did I tell u I worked there...silly me
