Bouchon is pretty good but it seems to be going downhill. I've been several times in the last couple of years. Initially, I would've given this place 5 stars, but my last visit was just meh, so I'll give this an average of 4 stars.
They previously had octopus on their menu, which was excellent. Their bread and foie gras are also excellent. Their cheeses are pretty good. Salads are also pretty good. Everything else I've tried on their main menu hasn't been memorable (I can't even remember what they were).
In general, if I were to go back, my strategy would be to order items not in the main course section, and it will probably be pretty good.
