Prague

Czech Republic is the homeland of Pilsner Urquell, the land of Saaz hop and where the lager beer born. Since then, there was no great improvement in beer: you can find good (and bad) pilsner at a good price (2-3€ per liter), a dark beer (kind of a schwartzbeer) and nothing more: one of the most innovative beers here is the Staropramen unfiltered lager. I still can't understand why you ferment at low temperature to have a clean taste, and then leave a lot of yeast to make the beer hazy and add yeast flavours and off-flavours.
I visited this pub: http://www.praguebeermuseum.com/ with 30 taps, almost all lagers from Czech Republic, I tasted a Cerna Hora Qvasar that was badly stocked and was stinking, and a 'moravian ale' with Saaz hops higly fermented: well, it's a waste to charge such noble hop with ale esters.
Here is a good brewery, close to Petrinske Sadi park http://www.klasterni-pivovar.cz/. They have good lager (obviously), but also Weizend and a IPA: classic and simple with Amarillo and Cascade, the kind of american IPA I really like.
To have a good and cheap dinner check here http://www.kolkovna.cz/ the Pilsner Urquell restaurants. But the best Urquell I tasted was the tank one at the bar on top of the Riegrovy Sady park, fresher and with more intense hop flavours.
If you walk around Loretanska street, there is a small bistro with no name; hey just talk in czeck but have menu in different languages, so it's perfect for a cheap lunch and a good beer.
