A game I loved as a child and now play with my kids is called "My father owns a grocery store", a guessing game that you can play anywhere, anytime.
You say..."My father owns a grocery store and in it he sells something that begins with (insert letter that begins the item you are thinking of, for example pretzels - say "p")" Then let the kids go wild trying to guess everything you can eat that starts with that letter. Whoever guesses it first gets to choose the next item (it has to be something you can eat to narrow down the field; otherwise you'd never get it!). Even very young kids love this game, though sometimes they need a little help. I've actually had complete strangers jump in when we are playing in public! It's almost contagious

It's more of a challenge than it sounds as lots of things begin with the same letter; you can go for quite some time before someone guesses correctly. Sometimes a helpful hint is needed if they start to get discouraged, but it's a great game to have in the back of your mind for those restless waiting around times when the kids get antsy.
