Restaurant recommendation in Paris

Hello,

I'm looking for a restaurant recommendation in Paris.
I'd like to have some excellent food (any style, really). I'm not into the super high class 3 star restaurants where service and process sometimes seems to be given more importance than the actual food. I'd also like to stay away from where the super rich go.
Normally I like restaurants of either young new chefs who try to make a mark but are not spoilt by the pressure of success yet and still have ambition to create good food or, very classic, been around forever restaurants...
This is just for me on my own as part of a business trip (I do like having nice dinners on my own though)
Any recommendations? (sorry, this is super vague, I know).
