Stopped by Subway on a Sunday evening (most things in Berlin are closed on Sundays). They have…read moretouch screens which you can select English or German to order on. I feel like Subway is a less than ideal place to have ordering screens even though I usually prefer not having to talk to anyone.
Strangely they don't have many deli slices here, only ham. Chicken is chunks and they didn't have turkey. So I went with tuna instead. They let you pick sauces but it's hard to tell how much sauce is in the tuna to begin with so I'm not sure it's great in practice. They also were out of a few different bread types but the screen didn't reflect it.
Anyway, service was fine but it was a little frustrating.
