After visiting the Prague Castle, this cute little cafe is the perfect spot for a light lunch, cappuccino or pastry. Very reasonable prices and very friendly staff.
If you are a nonsmoker, avoid this place. Usually very smokey, but if you are looking for a reasonable food in the area, it is quite ok.
We ate here on Friday night, quite empty. If you want cheap and good food, then do not hesitate to visit. Here's a typical pub menu with a good Czech beer and friendly service.
