I know it's not cheap and I know there is a major mark up but I am sure when I went to see &Juliet a glass cost about £7.
Went to see Ghost story last night DSD likes rosa prosecco so treat us both to this and it was over £31?
It was Champagne wasn't it? Surely prosecco can't be over £15 per glass. 

I do hate wasting money but live and learn.
