Gridskipper's Amanda Kludt put together a list of ten places to eat late in Paris, for people like myself who need to get something to eat after midnight in between bars lest we pass out.
Kludt on Pied de Cochon: "This 50-year-old restaurant specializes in piggie parts, and they serve them 24 hours a day. They are one of the most famous brasseries in Paris and manage to have a pretty steady patronage even in the wee hours. Try the pig snout, the pig tail, or if that's a bit much for you, a large pile of shellfish." I know where I'm going the next time I'm out drinking in Paris!
