You can do any character meal and it will be wonderful. When we celebrated my DS's 7th birthday we did the Birthday celebration with Pat E. Cake at the Plaza Inn. It was $10 per person and we each got a plastic cup/straw filled with fruit punch. Everyone also got a cake to decorate with frosting and sprinkles. We had the grandparents and some friends with us too and all of us had a great time. Mickey and Minnie came to take pictures with all the guests and when you purchase the pictures they can change the date on the picture to reflect the actual birthday if you want.
Be sure to get your birthday badge/sticker so all the cast members say Happy Birthday! The kids love this!!!!!!!
