We had the chance to visit Olympic Park or Olympiapark, as written in German last September 2009. I always see this park everytime we pass-by Munich when going to other places in Bayern or Bavaria. It was only last September that we had the chance to enter inside. You can go walking around the area but if you want to go inside the Olympic Stadium, you will have to pay for an entrance fee. If I am not mistaken we paid around 4.00 Euros per person as we went inside. I never see anybody wearing tuxedo vest during our visit here. I guess in special occasion where prominent people visit or perform a social activity here like concerts and gala, for sure you will see a lot wearing formal clothes including tuxedo vest.

Here I am striking a pose at Olympia Park in Munich, Bavaria.
The Olympiapark in Munich, Germany, is an Olympic Park which was constructed for the 1972 Summer Olympics. Found in the area of Munich known as the "Oberwiesenfeld" ("upper meadow-field"), the Park continues to serve as a venue for cultural, social, and religious events such as events of worship. The Park is administered by Olympiapark München GmbH, a holding company fully owned by the state capital of Munich. wikipedia
