I wouldn't say it's very cheap. The first 0.5l of house beer was just under 6 Euros, and the second bottle of craft beer, plus each of the snacks were under 7 Euros if I remember correctly. But bearing in mind this was the Old Town where there's a lot of tourists. We stopped for coffee a few times around the city, and my usual go to cappuccino was around 3.5 Euro, which was around the same price as I had in Poland and Estonia on my same trip.
