Beer gardens have a long tradition in Munich. King Ludwig the first is to be held responsible for allowing brewers to server beer outside the "Braustube" (brewer's locale). Outside meant above the cellars where beer could be kept cool without available refrigeration. To keep the cellars cold chestnut trees were planted for shade. The not so wealthy citizens of Munich could not afford the food served but the brewers did not want to miss their business. A compromise arose letting people bring in their own lunches and dinners as long as they bought the beer and sat down at tables without table cloths. This is still true today.
