Official pricing for “The New Mel Brooks Musical Young Frankenstein” has been set and the top ticket for one of the best 100 seats in the Hilton Theater will carry a $450 price tag. Other seats will go for $120, $80 and $60. Those hefty price tags will apply on Friday and Saturday evenings in addition to weekend matinees. The prices for weekday viewings will be reduced with the producers planning to reveal a $25 orchestra seat for a very select few.
