There's Dave & Busters. You could give each girl a $10 game card and let them play for a while. Then have dinner at the restaurant. It's not as secure as Chuck E Cheese but there's tons of games and she'll have lots of fun.
Are interested at all in the sleepover option? You can limit it to 5 friends, let her pick out some movies at blockbuster, and order pizza.
If you have a hair salon you frequent, check with your stylist and see if she or anyone she knows does parties. I've known some stylist who would come to your house and fix the girls hair, put a litle makeup on them, and maybe do their nails. Makes them feel real grown up.
You could also just take her and her friends to a nail salon. They usually do a "polish change" for around $5. For an extra buck they can get a flower on their thumbnails. Then go out to eat somewhere.
OK. I'm out. My daughter turned 6 this year and we still had a dress up party at our house with a moonwalk in the yard. Next year is probably going to be tough. Good Luck
