Beer prices in European bars and bricks as reminders

We were celebrating my mentor's b-day in a bar downtown. 0,25l of beer cost €4,5, while 0,5l of beer (more or less a pint) cost around €8,60 and 1l beer cost €16. That's Paris downtown for you. Since it was happy hour I ordered 2 pints of beer for €10, which, according to a floor mate at the Brazilian house, can be considered okay in Paris.

A pint of beer in Budapest costs between €0,85 and €2,50 depending on the bar you're in. At the airport I saw a price label of €3 which made my wallet tremble in fear and then it quickly ran away.

In Switzerland it is more common to order 0,33l of beer. A standard beer bottle you can get in shops contains 0,33l beer, too, but 0,5l beer bottles are also available. On the countryside 0,33l of beer cost on around 5 Swiss francs and 0,5l beer cost 7 Swiss francs in a bar. Pretty much Paris downtown prices. I don't want to imagine how much a beer costs Zurich downtown...

Tell me, how much does a certain quantity of beer cost in your (unmentioned) country?

By the way, in the end I forgot my bag at my mentor's place. If I had carried something heavy like a few bricks instead of a single paper notebook I'm sure I would have missed the weight on my back.
