Maz or Sezanne, Tokyo

Unfortunately I have to decide between the two as both only have openings on the same day.

I have a lunch reservation for L'Effervescence so Im leaning towards Maz to avoid two French courses but Sezanne has a stronger reputation overall. But Ive also been reading some mixed reviews of Sezann where its hit or miss since the previous chef left.

Anyone been to both venues recently and care to comment?
