Trip to Germany was great! We stayed with daughter, son-in-law, and new grand-daughter, so eating out was not an issue. The commissary on base had a lot of gluten-free grocery options, and the German drug store we went to had tons of Dr. Shar products. There were some I had never seen before, especially in the variety of breads, cookies, and assorted sweets. We even found some gluten-free beer in a shopping mall in Bayeruth (sp?)
We flew non-stop from Chicago O'Hare to Munich and back on United. The gluten-free dinner on the flight out was very good according to hubby, but it went downhill from there. The "breakfast" was a rice cake and applesauce. The lunch and snack on the flight back were barely tolerable. They seem to think rice is the only carbohydrate acceptable for gluten-free diets.
I wish I had more information on eating out in Germany, but with a 2-week old baby, getting out much was not an option. We did make it to a street festival in Nuremburgh, and enjoyed brats and wine. Among all the food and souvenier tents, there was a gluten-free tent with about the best cookies hubby ever had!
Since they will be there 3 years, we plan on going back in about a year or so. Hopefully, we will be able to get out more.
So, I'd recommend bringing your own food on United Airlines - they tried, but came up a little short.
