Great report, looking forward to more! A pity you don't seem to enjoy Glühwein anymore, but it's okay, Glühwein is not for the weak

German Railways indeed doesn't have any complimentary food or drinks on board (apart from gummy bears or tiny chocolates they sometimes give out as gifts in the 1st class). But first class passengers can visit lounges at large stations, which have coffee and soft drinks. Lounges in Munich, Berlin, Cologne and Frankfurt also have dedicated 1st class sections with beer, wine and snacks (sandwiches, sometimes soups, cakes etc.)

For future Munich visits, keep in mind that the BMW Welt also offers per-hour rentals of many interesting BMW models.
