We did the Fantasmic Package on the DDP on January 6, 2008 at Mama Melrose. Everyone got to pick an appetizer, an entree, and a dessert. We had the pay the gratuity separate. We were a party of 10, and each room just charged their gratuity to the room. (We were automatically charged 18% because of our group size.)
And as a side note.... I had read mostly negative reviews of Mama Melrose, so I made a huge disclaimer to my group -- asking for forgiveness in advance.
There was no need -- this meal was excellent, and we have many food snobs in our group. I highly recommend this place!
