Prague is a fantastic place to go for a pivo (a pint). Great price and great quality. A half litre will cost you around 15czk, up to 30czk in the city centre. That's just 60-1.20€ approx. for a fresh, smooth Prague pint.
Try white beer (Pšeničné pivo) or a light pint (Světle), an orange one (Polotmavé), dark (Tmavé) or black (Černe).
Prague lagers include Staropramen, with its brewery in the Smichov district and Branik. Popular local beer varieties range from Pilsner Urquell to Gambrinus; Prague's favoured brew.
