This was a nice and cozy breakfast experience and cool to have visited the place from the actual Amelie de Montmartre movie!
We enjoyed a typical Paris breakfast here with eggs, croissants, good strong coffee, etc. Staff was polite and flexible on how we butchered the pre-set menus, so the fact that service was a bit slow wasn't that upsetting.
Don't know about lunch and dinner here since breakfast was all we had - but I would say that this is a good option regardless of time of day.
Give it a try and enjoy!
