Went to a jazz bar on the rive gauche tonight with another au pair, who it turns out also lives close to St Germain en Laye! This came in handy when we missed the last RER to the end of the line, and had to get a taxi from Rueil Malmaison. This was a good learning experience for me, though - it turns out Ruiel Malmaison is actually super close to Le Vesinet by car, and so if I miss the last RER to St Germain but can make it to Rueil, I'm good because the taxi ride will not be super expensive.
Anyway, the jazz was good, it was a little soft for me though (I prefer more lively jazz, with horns; this was a band with piano, contrabass, drums, and a flute). The atmosphere was nice, and there were actually quite a few people there. We're going to try to go to some more jazz bars in the future, her host family is really into jazz and can tell her all the places to hit. We went to a cafe afterwards and had dessert; I had a creme brulee, and it was delicious. Speaking of delicious French desserts - I found a Laduree in St Germain des Pres, and although I didn't go in for a macaron because there was a line stretching out the door, I'll be going back on a wednesday or something to try one. I tried Pierre Herme last weekend and it was delicious, so now I have to try Laduree to compare.
