Here is some touristy stuff for Prague:
I enjoyed the Astronomical Clock in Pragues old town square. For something installed in 1410 its an engineering masterpiece.
If you want some good views Petrin Hill is nice and you can go up the tower there.
While I was there I was also partial to a good Trdelník.
But as some said beware of scammers, my mother got tricked out of a decent amount of money there.
