I thought this would be a well discussed topic (and perhaps it is, but nothing pops up on my forum search).
I'm planning on taking 1 long distant train, Paris->Irun (nearly 6 hours) and 2 overnight trains (Irun->Lisbon and Lisbon->Madrid). I see that the Paris->Irun train is a TGV and has some sort of cafe-bar offering sandwiches and snacks. This appears to be somewhere you must walk to, I don't see any mention of an at-seat service on the SNCF site (you can get it on a handful of TGVs but not this particular one).
For the the 2 overnights, my choices seem to be a cafe-bar only. Again, looks like you must walk there, there's no at-seat service. And I can't find any menus or anything online about what's on offer.
Since I'll be travelling solo, I'd feel uncomfortable leaving everything at my seat to go stand in a queue, so if there's no at-seat service, at least I know ahead of time to pop into a handy Carrefour for some snacks. Having said that, I am planning on getting a sleeper for the 2 overnight trains, so at least I can lock my room and go to the bar, if that's the case.
So, can anyone confirm the dining arrangements on these 3 trains in particular? Also, if you've tried it, what's the food like on these trains?
