In line with many other chains in the same category, I prefer others slightly more but in the end it comes down to taste because the quality, quantity and price are very similar.
A 10/12 euro sandwich with chips will fill you up in the end so if you want you can have a good dinner or lunch without spending a lot.
It's great that they have a gluten-free menu that's difficult to find in most places, and the sandwich we tried wasn't bad at all.
