If you're a kid, however, the reason why you will remember Easter is the fact that there's a ton of chocolate! Especially Easter Eggs that, in Brazil, consist of hollow eggs made of chocolate.
I am just bumping this thread to make sure a Polish or Czech person sees it. :D
In Britain, it's all about chocolate eggs; the traditional meat for the dinner is lamb. (Since most British people are not Catholic, we don't usually observe the not-eating-meat that some other countries do, like Jan's example of Brazil.)
