I used to get choucroute plates in Alsace and in Paris when I lived in France. I recently tried the choucroute at Sandrines in Harvard Square - it bit the bag. I couldn't believe how "chemical" it tasted.
I make my own choucroute garni at home - but is there any restaurant in greater Boston that does a good one? It's a great cold weather dish - and the cold weather in Boston appears to be passing into early spring. Not too soon for me :-)
