Take a taxi into town and book the return pickup when they drop you off. Saves all the messing about.
Also file your return flight plan before going into town, then all you need to do when you get back is hop in and go.
We haven't been for a while but last time we went to
Cafe des Arts
80 rue de Paris
phone 03 21 05 21 55.
Very nice meal in the centre of town at a reasonable price.
