The Christmas markets have started in Munich from 27th of November. Its pretty but expensive.
The atmosphere is quiet festive other than some stray idiots thinking that it is Oktoberfest. Leaving that part aside, it is a beautiful time of the year with the cold weather and smell of good, fresh and piping hot food.
If you wish to visit this place make sure you do it on a weekday. On weekends its less about enjoying than finding your way through throngs of people.
Happy Holidays People!
