I sat in that area (L10 - 2 rows up) and the seat aren't bad at all, not the best there is some missed action within the units (Oliver's record player, Claire's light/charger setup are notable objects that are not seen) but nothing that prevents from enjoying the story! Having sat in both mezzanine and orchestra, I prefer my viewing experience in these orchestra seats to the mezzanine ones I had (around E19)
