Thanks, everyone! Looks like somebody else was looking for just the same thing...
We're visiting Paris in June and would like to eat dinner at a mid-priced (by Paris standards), hip Paris restaurant with a younger crowd. By mid-priced, I basically mean not 170 euros per person like Taillevent or a similar top-drawer place. Something up to around 100 euros would work. For this meal we'd prefer decor that is more modern and less ornate.
I'd appreciate any thoughts!
