Yes the studios have paper bowls, and they are small. I would picture a little nut bowl. You can ask for more studio supplies. I bring Glad bowls with lids for cereal and sometimes you do need to store some leftovers
We take the gladware type bowls as well. I usually get 4 for $1 at the dollar store. I just throw them away before coming home and don't mess with cleaning and repacking them.
