Taco salad - what do you use?

We are going to have walking tacos for our daughter’s birthday party. We plan to get some of the personal sized bags of chips for the kids to use and eat out of since we thought they would find that fun. Because many of the adults have larger appetites, we thought getting the regular sized bags of chips would be good and they can take as many chips as they want.

Would you have plates or bowls for the adults? Or would you just do the personal sized bags and they can make more than one if they are still hungry? Or dump two small bags out onto a plate/bowl if they want?

We’ll have other food too (pretty much everything the very hungry caterpillar eats since that’s the theme).
