Beer is delivered as a 1-litre serving (a maß), directly to your table by friendly waitress' in traditional attire. Many visitors start drinking at 10.00am and don't finish until 11.00pm, by which time they're standing on the table linked arm and arm with complete strangers and singing along to Queen.
If you can avoid the temptation to go overboard on the beer, there are plenty of other attractions to see outside the tents. The typically efficient U-Bhan - the Munich subway train - is ever-waiting to whisk you back home. We may not be back next year, but this won't be the last trip to Oktoberfest.
