I think it depnds on your situation.
For us we are doing the package at Mama Melrose ($29 per adult, $10 per kid).
We have 3 kids (6, 4, & 2), so waiting online to get into the theater (one hour minimum from our past experiences, but usually 90 mins) is just NOT a good option with little ones.
For the price of the meal, and the amount we get, I think it is a GREAT deal. Plus we know we have reserved seating so we dont have to worry about waiting on the crazy long line.
I am looking forward to the dinner package!
