Oh I've not tried anything sweet at Le Crobag, just the ready to go sandwiches. The sandwiches were along the lines of a bocadillo/flauto with some veg, cheese, and a bit of meat like you might find in Spain. I much prefer the mini baguette to the pillowy white bread you might find at a train station sandwich in London.

If you are looking for really good backery stuff (in Germany), you won't find them at the airport/train station at all, as these are nearly universally only served by large chains, none of them especially known for being above the standard.

Sure, that's true nearly anywhere though. Relative to train stations in other countries I found Le Crobag sandwiches to be consistently fairly light compared to what I've found in London stations (e.g. really starchy pasties, hamburgers, and other sorts of things that just looked like gut bombs). Pret must have some presence at tube stations, but I haven't see any.
