Thanks for all the replies. Well I didn't get to do as much as I'd hoped. If anyone else is going, I would really recommend the best western Corona Hotel in Pimlico, its really central, rooms are grand (irish grand not royally grand), free papers, free internet in foyer, mens health mags, and best of all, 2 mins around the corner from Cask pub and kitchen.
Only got to Cask twice, nice tap line up, modern place, only real grumble was the Stone IPA was 3.50 for half on the menu, and when I went to order it they were charging 4.75 for it, they weren't budging either when I questioned it , and they didn't adjust the menu either the next day.
Went to Byron Burgers (chain) also, they sell a few beers too, I went for the Byron Pale ale brewed by Camden, nice if unexciting. The burgers were very nice, about £16 for burger, skinny fries and small can of beer.
Went to Oddbins on London Bridge and they had a decent selection of London Brews, I just got Kernel, Wilde Beer, Crafty Dan(brewed at a big brewery I think).
Would recommend the Imperial War Museum too, its free in, and I only got 2 out of 5 floors done in 5 hours. I had enough then. Outside the grounds of IWM I went to a blue pub on the corner called Grand Union, the burger there was also very good, and they had a few crafts also, i had a collaboration between Dogfish head and some English brewery, it was pretty watery and average "Charles Wells / Dogfish Head DNA New World IPA.
Basically thats all the info/tips I have.
