Not a pub but the Royal Festival Hall has a bar and plenty of space to drink. Drinks at the bar cost roughly the same as in a London pub. If you want to drink on the cheap you can also bring your own cans. The best feature of the Royal Festival Hall, however, is not its free WiFi but its large balcony overlooking the Thames. If you are happy to ignore that it is winter you can enjoy a pint there taking in the sights. The Royal Festival Hall is a pleasant 15 min walk away from LSE taking you over the Thames and its architecture is something to appreciate on its own: back in the day they truly believed this is what the future would look like.
Most pubs in London – especially around LSE – close at 11pm. If you want to continue drinking later than that, you’re advised to find a pub which allows you to do that in advance, as your options are a bit limited. A beer in a central London pub is between £3.50 - £4.50. You get your beer from the bar and you do not tip the bar staff, they might chase after you to return your change.
