Hi J.,
I have had the same issue in the past, and just wanted to throw it out there for you. If about half or more of the 35 people are going to be kids, you may consider doing 2 menus, I have ordered pizza for the kids, and had a separate, adult type meal for the grown ups. At eight years old, it's tough to find an "adult" meal that the kids will also enjoy. I love Cheryl's idea for BBQ pork (and might do that myself!). I have cooked meals like steaks, rib roasts. I have also used two variations of the same dish, like making "regular" spaghetti for the kids (which most kids love), and a chicken/shrimp and tomato alfredo spaghetti for the adults (who can always have the regular spaghetti too). Two sauces and one big pile of noodles, throw in a tossed salad and some garlic bread and you're set!
Good luck with your party!
P.
