I love prague!
The exchange rate is particularly awesome, so everything is pretty cheap.
You should go to Dvorak. He was a playa of the compositional sort.
this place has fantastic crystal, glass, etc. I got my mom a really nice candy dish that would be $200+ in the US for about $70. Ya ya!
The old towne square is really neat. The street vendors you can get anything from puppets (check out the puppet opera, actually!), to hot wine to WHIPS

(try getting that home through customs without a few raised eyebrows). There's a really nice cafe there called the grand cafe praha, I think. It has spa cakes with sugar and nuts and... oh, I could so go for one, but they aren't sold in the US!

The gelato on the 2nd floor is to DIE for and only about $2 USD.
Watch out for pickpockets, though. It's nutty.
edit:
oh, and the Czech national bridge and the castles are AMAZING. I'll dig out pics.
edit again:
at this late hour, this is the only pic I can find

this amused us highly because we were a symphony tour group from texas. Hee. They had a confederate flag up!!
