Care for Some Water?
You won’t find a Czech restaurant that will serve free water and you won’t find a Czech restaurant that will serve tap water. At the same time, basically every Czech restaurant offers at least one brand of mineral water, which often comes in several varieties: still, lightly sparkling and sparkling. Mineral water, even Czech made, is usually more expensive than Czech beer, sometimes almost twice as much.
If you ask for mineral water at a U.S. restaurant, you may get a confused look from the waiter. Your large glass of iced tap water will arrive free of charge as soon as you sit down and it will be refilled throughout your meal, but mineral water or simply bottled water seems to be an exotic product at many establishments.
