Crowds, oompah music, beer, singing, crowds, clacking mugs, bustling waitresses, crowds, roast chicken, pretzels, body heat, Bavarian clothes, softball sized dumplings, noise, pork knuckles, radishes, and silly hats. The crowd arriving at the U-Bahn station was the biggest, most tightly packed I have experienced. I skipped the carnival rides. It was a challenge to get into a beer tent without a reservation and a further challenge to find a seat. Wear traditional clothes and speak German to improve your odds. The crowd was unbelievable with harried waitresses letting it be known they did not appreciate blocked aisles. Somehow the waitresses carry six one liter mugs in each hand, five in the fist and one balanced on top.
The band played a number of German songs before switching to "YMCA" and "Hey, Jude" and the like before switching back to German. The mug filling operation ran with precision. Waitress dump any dregs and feed mugs into a washer for speedy refilling.
I have been twice, solo, and had a blast both times. I assume smoking is now banned. Never saw any vomit or public urination. I nursed two liters and left before closing.
