So yeah, as the title says I'm going on as business trip to the UK in a few weeks and I'll have a weekend free in London at the start. I arrive at Heathrow around 10 am the 30th, and leave for Louton the 1st in the afternoon. I already plan on visiting the British Museum to see the Rosetta Stone and other historical stuff. Other then that, the very rough outline includes finding a good whisky shop (I love me some scotch) and a place to enjoy a plate of fish&chips with a pint of bitter. I'm afraid I know very little about London and I haven't done the tourist thing since I was 14 so I'm a bit out of practice, so I come here for help.

So, Londoners and experiences globetrotters, what to do with a weekend in London?

Also, I'll be spending a week in Louton and a few days in Poznan in Poland, so if there are some things there I shouldn't skip feel free to share

Thanks
