Oktoberfest at Bierschenke
Time Out says
Giant steins, cold warehouses and questionable promotional material of women in dirndls: Oktoberfest in London can be unbearable. Trying to find a good one is just chasing a luftschloß (that’s German for an unrealistic dream, or ‘air castle’ if you want to get literal about it). But if you’re going to go for it, try and find one that at least vaguely resembles a Munich beer hall, like Bierschenke in Liverpool Street. It’s been at it for a decade, serving up traditional Bavarian wurst to thousands of Londoners every year. And unlike a lot of other soulless stein-peddlers, entry for this one is free.
