From the two places you mentioned, I'm assuming you live in the Macomb County area...
We are having my sons 4th Birthday party at Papa Ramono's at 23 and Schoenherr. It's $5 a child and they get a tour of the pizzeria (it's not just a take out place), they get to make their own little bambino pizza's, watch them bake and then of course eat them :) There is no time limit for how long you stay in the dinning area. You can come in early to decorate. And we have one child who is allergic to milk products, so they are even letting us bring in special dough for his pizza. We are having 10 kids and it's only $50 plus drinks. Also, I bought the kids aprons to wear at the pizza place as their gift/grab bag and I am writting their names on them in cool colors. Also, the pizza place gives each child a bag with crayons, coloring book and a coupon for a free bambino pizza on their next visit.
We had his 3 year party at Chuck E Cheese, and even though the kid had a blast, I felt so rushed and the pizza there is horrible, in my opinion.
The bouncy places are great also, but I can't afford another $350 this year for a birthday party.
Good Luck!
