In June the campfire will start at 8PM.
You can bring your own supplies for Smores. I have seen many people bring their own hotdogs also. We usually pack a cooler and bring some snacks, for some reason our boys think everything tastes better from the "chuckwagon".
They have pizza (frozen) and nachos, popcorn,candy,chips,soda,beer,hot chocolate and coffee. I wouldnt try to base a whole meal on their offerings.
Everything is good by snack bar standards, the prices are about the same for anyplace else in Disneyworld. Someone posted a link to the menu before but I cant recall where it was.
Tell everyone there we said "howdy"
