Currently enjoying a quick trip through Paris. We're staying near le Musee des Invalides in the 7th in Paris. We're looking for dinner options that aren't too far from there. We're way too late for any reservation at the Chateaubriand or any of the usually considered places, and besides we haven't packed much in terms of "elegant" clothes so we're looking for fun, casual options. Not necessarily bistro/french either. Not looking for astronomical prices but nothing ultra-cheap either.
Any hints/tips would be great, thanks!
