Hot dogs are Prague's ultimate fast food. Far superior to the New York 'dirty' dog, these are hollowed-out French baguettes stuffed with either a dark or white Bavarian style sausage, and topped with ketchup and/or mustard – basically the cheapest meal in town. The place to go for one of these is the Wenceslas Square.
Here's what Anthony Bourdain had to say about them when he dropped into the city:
There are 4 very important things to take into consideration though when buying a 'Prague Dog':
1. Visually review the sausage you want - You're looking for a juicy sausage, not one that's dried up and that's been hanging around for ages, I recommend avoiding buying at any of these kiosks during daylight hours. You really want to be munching on one at night when the turnover is high and when freshness of product is more likely.
2. Always check your change. Not all, but some of the kiosk workers like to make an extra income from short changing customers (especially easy to do I imagine when the customer can hardly stand up).
3. Also at night, be aware of your surroundings. The main square is frequented by pickpockets and taking out your wallet or purse to buy a Prague Dog will let the thieves know exactly where your money is. The price of a sausage is 50 CZK so just have 50 CZK ready in your hand already without having to show everyone where your personal bank is.
4. In the You Tube clip, Anthony Bourdain drinks a canned Pilsner beer. This is only recommended if all other bar options in the area are unavailable, or if you are shooting a Prague food and drink documentary with a vague product placement agenda. If not then enjoy that expensive can of tasteless beer anyway, which is a thousand times inferior to it's draught beer cousin.
Hezky den!/Lovely day!
