2 more quick differences:

1. There are tons of McDonalds in Prague, but instead of having trash cans, you just put your tray on a rack. I found that out after wandering around, looking for a place to toss my strawberry McFlurry.

2. You can't find cases, even 6-packs of beer. You just by beer in the grocery store, or even the liquor store, by the individual bottles. And you have your options, too; there's certainly no beer shortage in Czech land.
