Perhaps only at lunch time?
Since it's so beautiful and people linger for long time maybe I need to?
Planning early December visit.
I ask because another poster said she made a reservation for 11:45.
I’ve always found a table with no problem, but what is the harm in making a reservation?
I was there the first week of December a few years ago - there was a gigantic line waiting to enter the cafe early afternoon. If it's possible, make a reservation.
I settled for a Leberkase at the Christmas market outside - it was quite good.
