Euston Tap is one of my favourite boozers, tiny , 15 craft ales and beers on tap, reasonably priced, reasonably welcoming for kilt clad wanderers, 2 seconds from Euston station. Other great beer pubs - craft beer company, a few places across the city, about 25 hand pulled pumps with amazing beer, from £3 - £10 a pint, - brilliant. Draft house, close to the tower, sells unpasteurised pilsner urquell,. (Tankovna), tremendous. Always found London to be slightly cheaper than Glasgow to drinkdecnet beer. If you think it's expensive you either hover go out or only drink in yer Hoose. Can't wait for the 11th.
