Does barley coffee contain gluten?
Yes. Barley coffee is roasted barley, and barley contains gluten. It is a very common misunderstanding, because it gets ordered as a "lighter" alternative to coffee and the name does not sound like a cereal.
Eating out
At a bar, the machine that makes it is often the same one used for coffee: even choosing something else, there is contact.
Recipes change from one producer to the next and from one kitchen to the next: this is how something is usually made, not what is in the plate in front of you. The only answer that holds for your plate is the ingredient list on the packet, or the person who cooked it.
And how did it go at the restaurant?
Knowing what is in a dish is half the answer. The other half is what actually happened to the people who ate it in a specific place — and that is what SafeBelly collects: no stars, just how it went afterwards.
