One level below the Clock is a room filled with astronomical tools including a Meridian Hall. In the past, this was used to tell time.
This is for you if you intend on travelling during the most wonderful time of the year. With a number of markets - the main one being around Old Town Square, Wenceslas Square and a few scattered here and there, its a great place to bring in the holiday season. These markets are draped with lights and filled with a number of little stalls selling Czech festive food, ornaments, decor and other stuff. Many of them open around 10am and close around 9pm. We had most of our meals at the Christmas markets. They're so cheap and the choice is plenty.
If you bored of the food at the Christmas markets ( which is very unlikely ), visit one of the restaurants and try out some traditional Czech cuisine. We tried out a restaurant located near the Astronomical Clock. Some of the popular Czech dishes include - Guláš, knedliky, Smažený Sýr, Pork Knuckle and more. Take your tastebuds on a journey!
