I'd imagine you'd still be able to see things pretty well. The theatre isn't huge. Wish I could be more helpful, but I've only sat in the front of the mezz.
i've sat in Mezz F and the view was fine however everything above the fireplace from those seats was partially obstructed so I don't know how much worse itll get further back, but if uve seen it already than its not like youll be missing stuff
