Scope out all the menues for lunch counter services if you're feeding hefty-eating teens. While I think almost all CS portion sizes are large, some really deliver a lot of food value for one CS credit. For example, the Chicken & BBQ ribs combo meal at Cosmic Rays in the MK, and the BBQ ribs combo meal at AK...we are large folks and couldn't finish these meals (after walking all over the park for 3 hours, and having eaten only a very small breakfast of cereal bars 4 hours before lunch.)
