We're we robbed?

Went to seachurch yesterday for a dinner and show. It was really good, but the numbers dont add up. The show was 15 quid pp on its own, and the 'dinner and show' package was 106 pp. We went for the package. At the restaurant, the package only coverd 2 courses. So starter and main was about 40 quid total pp. So we got 40+15 of 'value' for 106. Seems mad. We'd have done it for half the price by not getting the package..... Anyone else ever seen this ?
