EXKi reminds me of Pret. They offer natural and organic ready to eat food for eat in or takeaway (cheaper). They do have a larger hot section than Pret.
I was initially tempted by a baguette but then chose a piadina instead. It was fine, with crisp flat bread and a lot of metled cheese in the middle.
Nothing that special but fine for a quick lunch on the go. I wouldn't go there for anything more than that.
