thank you all so much for all your recommendations so far! just thought of one more thing. we're taking the night train to barcelona on a tuesday from austerlitz. leaves around 8. do we need to grab something to eat before then? -- in which case it should be either (a) near our hotel on the left bank, or (b) near the train station (though in that case we'll be schlepping our bags). OR (c) perhaps there is food on the train that people would recommend. i know european trains ain't amtrak. recommendations for a place we can pop into unfashionably early, or should we wait for the train?
also, has anyone been to Le Train Bleu? http://www.le-train-bleu.com/trainbleu/ . Whoa. Curious.
thanks in advance.
