Quality alcohol is quite cheap out here, at least compared the USA (NYC in particular), and Budapest. No need for "duty free" here. When you order a drink, the waiter brings the whole bottle of Jack, Johnnie, or Beefeater, and pours, and pours, sometimes nearly a whole glass! That's with or without ice. So, quality not quantity, 3.50-6 $ is a fine evening out.

Sault!
