There is now a cafe that serves both warm and cold snacks. Hotdogs, chips, soda, and many other things including some healthy options not listed.
They only have snack vending machines. The museum is downtown surrounded by restaurant choices though, so you can leave and walk to the end of the block, eat and return to the museum.
You can buy snacks from the vending maybe or the gift shop
Theres a vending machine with snacks and drinks with a few small tables to eat at.
I think there is a little cafe.
