my son is watching a performance tonight and has just told me was charged 49 for two drinks...that cant be right..from the picture looks like lattes

Do they sell popcorn and that kind of snacks at the theatre?

For a cup of soda is $10 for each free refills ,and all candy bar's are $5 each it's pretty expensive , no outside food or drinks are allowed inside

Yes, that's probably right. Maybe he should purchase outside of theatre.

We did not purchase a beverage when we attended a show there, but the couple behind us did. He said that they paid $40 for two drinks. Therefore, I find it totally feasible.
